AB  - Irradiated fig pomace pyrochar (IrrPyrFP) is noteworthy as a novel sterilized low-cost sorbent of BTEX, pesticides, and Pb2+ ions. It was produced by applying pyrolysis treatment followed by gamma irradiation modification in order to obtain a highly efficient and sterile sorbent. The characterization of fig pomace before and after pyrolysis, as well as before and after irradiation of the obtained pyrochar, was done using SEM, FTIR, and elemental analysis, while its sorption ability was tested through the removal of examined pollutants by batch sorption experiments. The obtained results suggest that IrrPyrFP could play a significant role in the control of environmental pollutants, as indicated by the maximum adsorption capacities: 42 mg g−1 for BTEX, 0.625 mg g−1 for malathion, 0.495 mg g−1 for chlorpyrifos and 255 mg g−1 for Pb2+. A kinetic study showed that the removal process by IrrPyrFP mainly follows pseudo 2nd kinetics order, while the sorption equilibriums were estimated using the Langmuir and Freundlich model. Overall, the findings of this work suggest that pyrolysis and activation by irradiation of waste biomass is a promising way to produce sterile efficient sorbents for waste-water treatment based on green chemistry. Additionally, the demonstrated application of fig pomace promotes the potential of using this biomass for continual and economical waste management in the rising fig industry.

AB  - The removal of environmental pollutants is significant because of their harmful effects on living organisms. Biochar is favorable as a natural adsorbent of environmental pollutants due to its advantages, such as environmental acceptability and economic profitability. This study evaluated the potential of pyrolyzed plum pomace (PyrPP) as an adsorbent for environmental pollutants: Pb2+ ions, pesticides (chlorpyrifos and malathion), as well as organic pollutants BTEX. In order to ameliorate the adsorption capacity of PyrPP, modification by gamma irradiation was performed. Irradiated plum pomace biochar (IrPyrPP) has been shown to be an effective adsorbent, and the material is also sterilized by irradiation, which makes this material potentially sterile adsorbents of the most environmental pollutants from water. The irradiated biochar showed better adsorption performances for the removal of Pb2+ ions, BTEX, and chlorpyrifos. Maximum adsorption capacity (Qmax) of PyrPP for Pb2+, BTEX, chlorpyrifos, and malathion adsorption was 157.0, 17.6, 0.219, and 1.067 mg g− 1 , while Qmax of IrPyrPP for Pb2+, BTEX, chlorpyrifos and malathion was 271.0, 48.0, 0.428 and 0.593 mg g− 1 , respectively. The results obtained during this research suggest that biomass pyrolysis and modification of this biomass by irradiation is a promising way to produce efficient natural sterile sorbents for wastewater treatment.

AB  - A calcium-pyro-hydrochar (Ca-PHC) can be distinguished as a novel sorbent of Pb2+ and Cd2+ from an aqueous solution. It was obtained using hydrothermal treatment of the spent mushroom substrate (SMS), followed by a CaCl2·5H2O activation and pyrolysis. The characterisation of chars before and after modifications was done by scanning electron microscope (SEM), Brunauer–Emmett–Teller (BET) and Fourier transform infrared (FTIR). Batch experiments were performed to examine Ca-PHC’s sorption properties and binding mechanisms to selected metal ions. The maximum sorption capacities of Ca-PHC for Pb2+ and Cd2+ were 297 mg g−1, and 131 mg g−1, respectively. The obtained results demonstrated that the sorption of Pb2+ and Cd2+ by Ca-PHC follows a pseudo-second kinetic model and Freundlich isotherm. The binding of the selected metals onto Ca-PHC was enabled by the ion-exchange mechanism, surface complexation, mineral precipitation and cation–π interaction. Thermodynamic parameters indicate that metal ions binding by Ca-PHC are spontaneous and endothermic. Due to the high adsorption capacities, the obtained Ca-PHC has good potential for application in industrial wastewater treatment. In addition, the demonstrated use of SMS highlights another possibility of applying this specific biomass relevant to sustainable and economical waste management in the growing mushroom industry.

AB  - Redirecting waste biomass back into the economy can reduce their burden on the environment. The use of waste biomass for the production of fuels, value-added materials or natural fillers has significant economic and environmental benefits. Physico-chemical characterization of waste biomass (plum pomace and fig pomace) was done by proximate, elemental, biochemical analysis, FTIR and SEM analysis. The calorific value of both biomasses can be compared with the calorific value of lignite, which rises their potential use as a solid biofuel. The combustion behavior of biomass was investigated by thermal analysis techniques. Based on thermal degradation experiments performed at four heating rates a kinetic analysis of the biomass decomposition process was accomplished. The kinetic study was done using Kissinger method, Ozawa method, Flynn-Wall-Ozawa (FWO) method, Starink method, and Kissinger-Akahira-Sunose (KAS) method. The value of activation energy obtained by different kinetic methods was ∼210 kJ/mol for plum pomace and ∼162 kJ/mol for fig pomace. Estimated activation energy values were used to calculate thermodynamic parameters. In addition to the fact that the obtained results can serve as a useful reference for the design of pyrolysis reactors, this research has ecological significance because it solves the problem of solid waste disposal.

AB  - A series of nine 5-(4-substituted phenylazo)-3-amido-6-hydroxy-4-methyl-2-pyridones were synthesized and characterized by FT-IR, H-1 and C-13 NMR, UV-Vis, and PL spectroscopy. Photophysical properties of the dyes were examined in solvents of various polarities and at different pH values.

AB  - The antibacterial ability of in situ prepared nanometer-sized silver particles, immobilized in agar-agar films, was studied as a function of the concentration of co-dopant, magnesium ions. Content of inorganic components in hybrid films was determined using inductively coupled plasma optic emission spectroscopy, and found to be low (  lt  2 wt.-%). Morphology of prepared hybrid films, studied by transmission electron microscopy, revealed the presence of non-agglomerated and randomly distributed 10-20 nm silver nanoparticles (Ag NPs) within the agar-agar matrices. Fourier-transform infrared spectroscopy indicated the distinct chemical interaction between Ag NPs and polymer chains. Thermogravimetric analysis, as well as the determination of tensile strength, Young's modulus, and elongation at break showed improvement of thermal stability and mechanical properties of agar-agar matrices upon the incorporation of Ag NPs due to high compatibility between the hydrophilic organic component and inorganic components. The complete microbial reduction of Gram-positive bacteria Staphylococcus aureus was observed for all agar-silver films, while satisfactory results were observed for Gram-negative bacteria Pseudomonas aeruginosa (  gt = 99.6%). The release of Ag+ ions is suppressed by the increase of the concentration of Mg2+ ions and it was found to be significantly smaller (  lt = 0.24 ppm) than the harmful ecological level (1 ppm).

The structure of the synthesized compourtds has been confirmed by H-1 NMR,C-13 NMR, FITR, UV-Vis and XRD analysis techniques. The results obtained with thermogravimetric analysis (TGA) - derivative thermogravimetry (DTG) and differential thermal analysis (DTA) were combined with GC-mass spectral fragmentation to obtain thermal decomposition mechanism. Non-isothermal kinetics were monitored by application of TGA-DTG-DTA. For Kinetic behavior of the investigated dyes during their degradation in an inert atmosphere, Kissinger, Ozawa, Flynn-Wall-Ozawa (FWO) and Kissinger-Alcahira-Sunose (KAS) isoconversional (model-free) methods were applied. It was found that different thermal stabilities of investigated dyes are the consequence of their different chemical structures, including diverse substituents.

AB  - Alkyd resin/TiO2 nanocomposites (NC) were prepared from short oil alkyd resin and TiO2 nanoparticles (NPs) surface modified with in situ formed imine ligand, based on 3,4-dihydroxybenzaldehyde and oleylamine, or with three gallic acid esters. The short oil alkyd resin was synthesized from sunflower oil, phthalic anhydride, and trimethylolpropane. Unmodified and surface modified TiO2 NPs were examined by transmission electron microscopy. Rheological investigation revealed that prepared dispersions have higher dynamic viscosity than pure alkyd resin. Using different characterization methods it was obtained that NCs have similar thermooxidative stability as alkyd resin, lower glass transition temperature, better barrier properties, enhanced hardness, better chemical resistance, and lower adhesion to the metal, except in the case of NC prepared using TiO2 NPs surface modified with imine, which exhibited better adhesion to the metal than pure alkyd resin.

AB  - Atom transfer free radical polymerization (ATRP) was employed in a synthesis of graft polymer EVA-g-PMMAwith controlled length of side PMMA chains. Three steps of synthesis: partial hydrolysis of EVA, esterification with chloroacetyl chloride and ATRP grafting were performed to produce EVAOH, macroinitiator EVACl and grafted polymers G8020 (EVA/PMMA = 80/20 wt%) and G6040 (EVA/PMMA = 60/40 wt%). FTIR, Raman and NMR spectroscopy were used in the determination of the chemical structure and modification of EVA. Transmitted light and dark field microscopy showed higher affinity for coil formation of EVA-g-PMMA with longer PMMA side chains, i.e. G6040 compatibilizer. Morphological, thermal and adhesive properties of optical fiber adhesives of graft polymers and polymer blends poly(ethylene-co-vinyl acetate)-blend-poly(methyl methacrylate) (EVA/PMMA) compatibilized with 1 wt% of EVA-g-PMMA, were studied. Image analysis of SEM micrographs showed effective compatibilization with short grafted chains (G8020) that was indicated by lower porosity characteristics. TG/DTG analysis enabled determination of degree of hydrolysis and amount of chloro-functionalized groups. DSC analysis showed higher thermal stability of G8020 polymer. Single lap joint of adhesives/optical fibers were subjected to adhesive testing and obtained results for maximal force applied and adhesive failure suggested the visible influence of the length of graft chains on adhesion.

UPR, based on products of PET depolymerization, and NMF were characterized using FTIR, NMR, optical microscopy and SEM/EDS analysis. Cross-linking density (v), storage modulus (G'), damping factor (tan delta) and glass transition temperature (T-g) of the composites were determined from the DMA testing. Tensile (sigma(t)) and flexural (sigma(f)) strength, and micro Vickers hardness indicated good composite performance under static load. Thermal and flame resistant properties were analyzed by TGA/DTG and UL-94 flammability test whereby V-2 category of appropriate composite was achieved.

AB  - Optimization of the synthesis of cross-linked macroporous polymer impregnated with hydrous iron oxide and post-process of obtained material by application of freeze/drying technique, produces high performance adsorbent applicable for efficient arsenic removal. Characterization and analysis of adsorbent performances encompass material characterization, equilibrium and kinetic study, influences of interfering ions and modeling of adsorption data in ion free and competitive conditions. Kinetic study, i.e. fitting by Weber-Morris model and single resistance mass transfer model predicts intra-particle diffusion as a rate-controlling step. Thermodynamic parameters indicate endothermic, feasible and spontaneous nature of adsorption process. Competitive kinetic study in the presence of interfering ions shows low detrimental effect on both capacity and kinetic of arsenic removal. Visual MINTEQ modeling software was used for the prediction of adsorbent performances and interfering ion influences. Preliminary fixed-bed column study was accomplished by the use of Bohart-Adams, Yoon-Nelson, Thomas and Modified dose-response model. High arsenic removal capacity of 31.0 mg g(-1), at 25 degrees C, and multi-cycle reusability of ER/DETA/FO/FD, significantly affects the affordability of techno-economic indicators based on the operating costs of the process.

Competitive kinetic study in the presence of interfering ions shows low detrimental effect on both capacity and kinetic of arsenic removal. Visual MINTEQ modeling software was used for the prediction of adsorbent performances and interfering ion influences. Preliminary fixed-bed column study was accomplished by the use of Bohart-Adams, Yoon-Nelson, Thomas and Modified dose-response model. High arsenic removal capacity of 31.0 mg g(-1), at 25 degrees C, and multi-cycle reusability of ER/DETA/FO/FD, significantly affects the affordability of techno-economic indicators based on the operating costs of the process.",

AB  - Nanocomposites (NCs) with different content of silver nanoparticles (Ag NPs) embeded in polystyrene (PS) matrix were prepared by in situ bulk radical polymerization. The nearly monodisperse Ag NPs protected with oleylamine were synthesized via organic solvo-thermal method and further used as a filler. The as-prepared spherical Ag NPs with diameter of 7.0 +/- 1.5 nm were well dispersed in the PS matrix. The structural properties of the resulting Ag/PS NCs were characterized by transmission electron microscope (TEM) and Fourier transform infrared (FTIR) spectroscopy, while optical properties were characterized using optical absorption measurements. The gel permeation chromatography (GPC) measurements showed that the presence of Ag NPs stabilized with oleylamine has no influence on the molecular weight and polydispersity of the PS matrix. The influence of silver content on the thermal properties of Ag/PS NCs was investigated by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The results indicated that resistance of PS to thermal degradation was improved upon incorporation of Ag NPs. The Ag/PS NCs have lower glass transition temperatures than net PS because loosely packed oleylamine molecules at the interface caused the increase of free volume and chain segments mobility near the surface of Ag NPs.

AB  - Incorporation of surface modified TiO2 nanoparticles into polystyrene (PS) matrix was achieved by in situ bulk radical polymerization of styrene. The surface of TiO2 nanoparticles was modified with four amphiphilic esters of the gallic acid (octyl, decyl, lauryl and cetyl gallate), which have different lengths of hydrophobic alkyl chain (C8C16). FTIR and UV-Vis spectroscopy measurements confirmed the formation of a charge transfer complex between surface Ti atoms and gallic esters. Microstructural characterization of the synthesized nanocomposites revealed that the best dispersion of TiO2 nanoparticles in PS was achieved when the TiO2 surface was modified with octyl gallate. The presence of surface modified TiO2 nanoparticles by different alkyl gallates does not have an influence on the molecular weight and glass transition temperature of PS matrix. On the other hand, thermal and thermo-oxidative stability of PS were significantly improved by incorporation of surface modified TiO2 nanoparticles. The most pronounced improvement of thermal and thermo-oxidative stability was observed for TiO2 nanoparticles surface modified with octyl gallate. POLYM. COMPOS., 2013.

AB  - Nanocomposites based on poly(methyl methacrylate) (PMMA) and TiO2 nanoparticles were synthesized by in situ radical polymerization of MMA in solution. The surface of TiO2 nanoparticles was modified with four gallic acid esters (octyl, decyl, lauryl and cetyl gallate). The content of gallates present on the surface of TiO2, was calculated from the TGA results. The influence of length of hydrophobic tail of amphiphilic alkyl gallates on dispersability of surface modified TiO2 nanoparticles in PMMA matrix, the molecular weight and glass transition temperature of PMMA, as well as the thermal stability of the prepared PMMA/TiO2 nanocomposites in nitrogen and air was investigated. The influence of content of TiO2 nanoparticles on the properties of these nanocomposites was also examined. The formation of a charge transfer complex between the surface Ti atoms and the gallates was confirmed by FTIR and LIN/spectroscopy. TEM micrographs of the PMMA/TiO2 nanocomposites revealed that degree of TiO2 aggregation can be significantly lowered by increasing the length of aliphatic part of the used gallates. The molecular weight of PMMA slightly decreases with the increase of TiO2 content, indicating that used TiO2 nanoparticles act as radical scavengers during the polymerization of MMA. The presence of surface modified TiO2 nanoparticles do not have an influence on the mobility of PMMA chain segments leading to the same values of glass transition temperature for all investigated samples. Thermal and thermo-oxidative stability of the PMMA matrix are improved by introducing TiO2 nanoparticles modified with gallates.

AB  - A series of novel thermoplastic urethane-siloxane copolymers (TPUSs) based on a alpha,omega-dihydroxy-[poly(epsilon-caprolactone)-b-poly(dimethylsiloxane)-b-poly(epsilon-caprolactone)] (alpha,omega-dihydroxy-PCL-PDMS-PCL) triblock. copolymer, 4,4-methylenediphenyl diisocyanate (MDI) and 1,4-butanediol (BD) was synthesized. The effects of the content (9-63 mass %) of hard urethane segments and their degree of polymerization on the properties of the segmented TPUSs were investigated. The structure, composition and hard segment degree of polymerization of the hard segments were examined using (1)H- and quantitative (13)C-NMR spectroscopy. The degree of crystallinity of the synthesized copolymers was determined using wide-angle X-ray scattering (WAXS). The surface properties were evaluated by measuring the water contact angle and water absorption. In the series of the TPUSs, the average degree of polymerization of the hard segments was varied from 1.2 to 14.4 MDI-BD units. It was found that average values from 3.8 to 14.4 MDI-BD units were effective segment lengths for crystallization of hard segments, which resulted in an increase in the degree of microphase separation of the copolymers. Spherulite-like superstructures were observed in copolymer films by scanning electron microscopy (SEM), which are believed to arise from the crystallization of the hard segments and/or PCL segments, depending on the content of the hard segments. The surface of the copolymers became more hydrophobic with increasing weight fraction of PDMS. The synthesized copolymers based on a PCL-PDMS-PCL segment showed good thermal stability, which increased with increasing content of soft PDMS segments, as was confirmed by the value of the starting temperature of thermal degradation.

AB  - U ovom radu prikazana je struktura i neka svojstva serije novih termoplastičnih uretan-siloksanskih kopolimera (TPUSs) na bazi α,ω-dihidroksi-[poli(ε-kaprolakton)-b-poli(dimetilsiloksan)-b-poli(ε-kaprolakton)] triblok kopolimera (α,ω-dihidroksi-PCL-PDMS-PCL), 4,4'-metilendifenildiizocijanata (MDI) i 1,4-butandiola (BD). Ispitan je uticaj sadržaja uretanskog tvrdog segmenta (9-63 mas. %) i njegove dužine, tj. stepena polimerizacije, izražene preko broja MDI-BD ostataka, na svojstva segmentiranih TPUSs. Struktura, sastav i stepen polimerizacije tvrdog segmenta su ispitani pomoću 1H- i kvantitativne 13C-NMR spektroskopije. Stepen kristaliničnosti kopolimera je određen metodom difrakcije X-zraka na velikim uglovima (WAXS). Površinska svojstva kopolimera su ispitana određivanjem kontaktnih uglova sa vodom i merenjem apsorpcije vode. U seriji kopolimera dužina tvrdog segmenta izražena preko broja ponavljajućih MDI-BD jedinica je varirana od 1,2 do 14,4. Utvrđeno je da tvrdi segmenti sa 3,8 do 14,4 ponavljajućih MDI-BD jedinica efikasno kristališu, što je rezultovalo u povećanju stepena mikrofazne separacije kopolimera. SEM analiza je pokazala prisustvo sferulitne strukture u kopolimernim filmovima, koja najverovatnije potiče od kristalizacije tvrdih i/ili PCL segmenata, zavisno od sadržaja tvrdih segmenata. Hidrofobnost površine kopolimera je rasla sa povećanjem masenog udela PDMS-a u odgovarajućem uzorku. Sintetisani poliuretani na bazi PCL-PDMS-PCL pokazuju povećanje termičke stabilnosti sa povećanjem sadržaja mekih PDMS segmenata, što je potvrđeno porastom početne temperature degradacije, određene TG analizom.

The degree of crystallinity of the synthesized copolymers was determined using wide-angle X-ray scattering (WAXS). The surface properties were evaluated by measuring the water contact angle and water absorption. In the series of the TPUSs, the average degree of polymerization of the hard segments was varied from 1.2 to 14.4 MDI-BD units. It was found that average values from 3.8 to 14.4 MDI-BD units were effective segment lengths for crystallization of hard segments, which resulted in an increase in the degree of microphase separation of the copolymers. Spherulite-like superstructures were observed in copolymer films by scanning electron microscopy (SEM), which are believed to arise from the crystallization of the hard segments and/or PCL segments, depending on the content of the hard segments. The surface of the copolymers became more hydrophobic with increasing weight fraction of PDMS. The synthesized copolymers based on a PCL-PDMS-PCL segment showed good thermal stability, which increased with increasing content of soft PDMS segments, as was confirmed by the value of the starting temperature of thermal degradation., U ovom radu prikazana je struktura i neka svojstva serije novih termoplastičnih uretan-siloksanskih kopolimera (TPUSs) na bazi α,ω-dihidroksi-[poli(ε-kaprolakton)-b-poli(dimetilsiloksan)-b-poli(ε-kaprolakton)] triblok kopolimera (α,ω-dihidroksi-PCL-PDMS-PCL), 4,4'-metilendifenildiizocijanata (MDI) i 1,4-butandiola (BD). Ispitan je uticaj sadržaja uretanskog tvrdog segmenta (9-63 mas. %) i njegove dužine, tj. stepena polimerizacije, izražene preko broja MDI-BD ostataka, na svojstva segmentiranih TPUSs. Struktura, sastav i stepen polimerizacije tvrdog segmenta su ispitani pomoću 1H- i kvantitativne 13C-NMR spektroskopije. Stepen kristaliničnosti kopolimera je određen metodom difrakcije X-zraka na velikim uglovima (WAXS). Površinska svojstva kopolimera su ispitana određivanjem kontaktnih uglova sa vodom i merenjem apsorpcije vode. U seriji kopolimera dužina tvrdog segmenta izražena preko broja ponavljajućih MDI-BD jedinica je varirana od 1,2 do 14,4. Utvrđeno je da tvrdi segmenti sa 3,8 do 14,4 ponavljajućih MDI-BD jedinica efikasno kristališu, što je rezultovalo u povećanju stepena mikrofazne separacije kopolimera. SEM analiza je pokazala prisustvo sferulitne strukture u kopolimernim filmovima, koja najverovatnije potiče od kristalizacije tvrdih i/ili PCL segmenata, zavisno od sadržaja tvrdih segmenata. Hidrofobnost površine kopolimera je rasla sa povećanjem masenog udela PDMS-a u odgovarajućem uzorku. Sintetisani poliuretani na bazi PCL-PDMS-PCL pokazuju povećanje termičke stabilnosti sa povećanjem sadržaja mekih PDMS segmenata, što je potvrđeno porastom početne temperature degradacije, određene TG analizom.",

AB  - Incorporation of inorganic nanoparticles can significantly affect the properties of the polymer matrix. The properties of polymer nanocomposites depend on the type of incorporated nanoparticles, their size and shape, their concentration, and interactions with the polymer matrix. Homogeneity of polymer nanocomposites is influenced very much by the preparation method. In this study, TiO2 nanoparticles surface modified with 6-palmitate ascorbic acid (6-PAA) were encapsulated in poly(methyl methacrylate) (PMMA) by in situ radical polymerization of methyl methacrylate initiated by 2,2'-azobisisobutyronitrile (AIBN). The surface modification of the TiO2 nanoparticles was achieved by the formation of a charge transfer complex between TiO2 nanoparticles and 6-palmitate ascorbic acid. The radical polymerization of MMA in the presence of TiO2-PAA nanoparticles was conducted in solution (PMMA/TiO2-PAA-R), in bulk (PMMA/TiO2-PAA-M) or in suspension (PMMA/TiO2-PAA-S). The main purpose of this study was to investigate the influence of the preparation method on the molar masses and thermal properties of PMMA/TiO2-PAA nanocomposite. It was obtained that molar masses of PMMA extracted from the composites had smaller values compared to molar masses of pure PMMA synthesized in the same manner, which indicated that TiO2-PAA nanoparticles affected the reaction of termination. Thermal properties were investigated by DSC and TGA. The values of glass transition temperature, Tg, were influenced by the way the radical polymerization was conducted, even in the case of the pure PMMA. The Tg of composite samples was always smaller than the value of the corresponding PMMA sample and the smallest value was obtained for PMMA/TiO2-PAA-M since they contained the largest amount of low molar mass residue. The TGA results showed that thermal and thermooxidative stability of polymer composites obtained in solution and in suspension was better than for the pure PMMA obtained in the same way.

AB  - Poly(methyl methacrylate)/alpha-Fe2O3 Composites were prepared by in situ bulk radical polymerization of methyl methacrylate in the presence of the cubic alpha-Fe2O3 particles using 2,2'-azobisisobutyronitrile as initiator. The cubic a alpha-Fe2O3 particles were synthesized by forced hydrolysis of FeCl3 and characterized by X-ray diffraction analysis and transmission electron microscopy. The molar masses and molar mass distribution of synthesized PMMA samples were determined by gel permeation chromatography. The influence of alpha-Fe2O3 filler particles on the thermal properties of the PMMA matrix was investigated using thermogravimetry and differential scanning calorimetry. The molar mass and polydispersity of PMMA extracted from composite samples were not influenced by cubic alpha-Fe2O3 particles. The obtained composites have better thermal and thermooxiclative stability than pure PMMA. On the other hand, the values of the glass transition temperature of composite samples were identical to the glass transition temperature of pure PMMA.

The thermal and thermooxidative behaviour of the polyimide resins was studied by thermogravimetric measurements (TG) in oxygen and nitrogen. Polyimide resins have been irradiated (500 kGy) and their radiation stability evaluated on the basis of thermal and thermooxidative behaviour of irradiated samples. The thermal and oxidative degradation of the examined polyimides is complex and occurs in two phases. The first step occurs in both nitrogen and oxygen but it is somewhat less pronounced in oxygen due to oxidation and formation of more stable products. All samples showed very good radiation stability and there is almost no change in the first degradation step while the span of the peaks in the second step is narrowed and temperatures are slightly lower.
