AB  - One group of polymers that may help relieve the dependence on crude oil is based on itaconic acid, the biotechnological production of which has become feasible. Itaconic acid and its derivatives can easily be incurporated into polymers and may serve as a substitute for petrochemically derived acrylate or methacrylate monomers. The applications of polymers based on itaconic di-esters depend largely on their thermal stability. The thermal stability of poly(di-itaconates) is dependent, not only on the general structure of the monomer repeating unit, but also on the structure of the ester substituent. Depolymerization, initiated by b-scission or random main chain scission, is the dominant thermolysis mechanism in most cases. The deploymerization of poly- (di-itaconates) may be accompanied by de-esterification, elimination, cross-linking, random main or side chain scission and carbonization. Comparison of the thermal degradation mechanism of polymeric di-esters of itaconic acid to that of corresponding poly(methacrylates) confirms the viability of substituting poly(methacrylates) by poly(di-itaconates). .

AB  - The general literature procedure for the preparation of the reversible addition-fragmentation chain transfer (RAFT) agent 2-(2-cyanopropyl)-dithiobenzoate (CPDB) was modified by omitting the recrystallisation of the intermediate di(thiobenzoyl)disulphide. The yield of the CPDB in the simplified synthesis was increased four times compared to the standard one. The behaviour of the CPDB obtained by the modified procedure and by the standard one in the polymerisation of methyl methacrylate was investigated. The CPDB synthesized by the simplified procedure showed itself to be a good RAFT agent, giving excellent control over the polymerisation of methyl methacrylate and it behaved in the same manner as the CPDB prepared by the literature method. The obtained poly(methyl methacrylate) had a narrow molecular weight distibution (PD = 1.1).

In order to improve thermal stability of elastomeric materials, networks were prepared by adding some heat resistant isocyanurate rings as a junction points by catalytic cyclotrimerisation of telechelic diisocyanates. The thermal degradation kinetics of samples has been studied by means of high-resolution thermal analyzer SDT Q600 TA Instruments, under nitrogen atmosphere. The activation energy for the two step reactions of thermal decomposition of different species was calculated and compared.

AB  - Poly(methyl methacrylate), PMMA, was prepared by reversible addition-fragmentation chain transfer, RAFT, polymerisation using 2-(2-cyanopropyl)-dithiobenzoate, CPDB, as the RAFT agent. The thermal stability of the resulting polymer approached that of anionically prepared PMMA, as determined by thermogravimetry. This was the consequence of the RAFT prepared polymer having no head-to-head links and no chain end double bonds, which are responsible for the relatively low thermal stability of radically prepared PMMA.

Termička stabilnost PMMA sintetisanog RAFT polimerizacijom je slična polimeru dobijenom anjonskom polimerizacijom, što je pokazala termogravimetrijska analiza. PMMA sintetisan RAFT polimerizacijom pokazuje znatno bolju termičku stabilnost u odnosu na PMMA sintetisan polimerizacijom preko slobodnih radikala, zbog odsustva termički labilnih veza glava-glava ostataka monomera u polimernom lancu, kao i dvostrukih veza na krajevima lanaca.

AB  - The transfer constant to benzene in the radical polymerisation of di-n-butyl itaconate, DBI, was measured at 60 degrees C and found to have the value of 2.2 x 10(-3). This value is surprisingly high considering that benzene has no readily extractable hydrogen atoms and is usually considered to be a relatively inert solvent in radical polymerisations. The high values of transfer constants in the radical polymerisation of itaconates must be taken into consideration when planning the tailored polymerisation of these monomers.

AB  - The free radical copolymerisation of itaconic anhydride and methyl methacrylate in solution was studied at 60 °C. The copolymer composition was determined by 1H-NMR spectroscopy and the obtained monomer reactivity ratios were calculated, rITA = 1.35±0.11; rMMA = 0.22±0.22 (by the Fineman-Ross method) and rITA = 1.27±0.38; rMMA = 0.10±0.05 (by the Mayo-Lewis method). The synthesised copolymers were modified by reaction with di-n-butyl amine. The copolymer composition after amidation was determined by elemental analysis via the nitrogen content. Amidation of the anhydride units in the copolymers with di-n-butyl amine resulted in complete conversion to itaconamic acid.

Sastav kopolimera određen je 1H-NMR spektroskopijom i izračunati su odnosi reaktivnosti monomera, rITA = 1.35±0.11; rMMA = 0.22±0.22 (metodom Fajnman-Ros) i rITA = 1.27±0.38; rMMA = 0.10±0.05 (metodom Mejo-Luis). Sintetizovani kopolimeri su modifikovani reakcijom sa dibutil-aminom. Nakon amidacije sastav kopolimera određen je elementalnom analizom na osnovu sadržaja azota. Amidacijom anhidridnih jedinica u kopolimerima dibutil-aminom nastale su komonomerne jedinice itakonamične kiseline.",

AB  - The kinetics and mechanism of the thermal degradation of poly(diethyl fumarate) (PDEF) were studied by thermogravimetry, as well as by analysis of the thermolysis volatiles and polymer residue. The characteristic mass loss temperatures were determined, as were the overall thermal degradation activation energies of three PDEF samples of varying molar mass. Ethylene and ethanol were present in the thermolysis volatiles at degradation temperatures below 300 degrees C, while diethyl fumarate was also evidenced at higher degradation temperatures. The amount of monomer increased with increasing degradation temperature. The dependence of the molar mass of the residual polymer on the degradation time and temperature was established and the number of main-chain scissions per monomer unit, s/P-0, calculated. A thermal degradation mechanism including de-esterification and random main-chain scission is proposed. The thermal degradation of PDEF was compared to the thermolysis of poly(ethyl methacrylate) (PEMA), poly(diethyl itaconate) (PDEI) and poly(ethyl acrylate) (PEA).

AB  - Gel casting, a novel method for molding ceramic powders, based on the synthesis concepts of polymer chemistry and traditional slip casting, has been investigated. The process comprises the casting of a stable suspension, prepared with high solid content (ceramic or metallic powder) and an addition of water soluble organic monomers (monofunctional and difunctional-crosslinking). The key role of the process is in situ polymerization of the organic monomers which form a hydrogel that acts as a powder binder. The gelled parts subsequently undergo drying, machining, burning out and sintering to produce a final ceramic body. In this study, the alumna was used as a model ceramic powder.
AB  - Ispitan je savremeni postupak oblikovanja keramičkih prahova, "livenje geliranjem", eng. gelcasting, zasnovan na konceptima polimerne hemije i klasičnog postupka livenja. Postupak obuhvata livenje stabilne suspenzije pripremljene sa velikom količinom čvrste faze (keramički ili metalni prah) i rastvorom organskih monomera, monofunkcionalnog i difunkcionalnog-umreživača, u odgovarajuće kalupe željene geometrije. Specifičnost postupka se ogleda u in situ polimerizaciji monomera u hidrogel koji služi kao vezivo praha. Gelirani odlivci se zatim suše, po potrebi mašinski obrađuju, termički tretiraju i sinteruju do finalne keramike. Kao model prah u radu je korišćen aluminijum-oksid.

AB  - The residues remaining after the thermal degradation of poly(di-n-alkyl itaconates) with ester substituents ranging from methyl to n-octyl were studied. It was found that the thermal stability of the polymers decreased with increasing size of the alkyl group. Depolymerisation was the main degradation pathway with the depolymerisation zip length being very small and independent of the alkyl substituent. The number of bonds broken per monomer unit, s/P-0, increased with increasing temperature and time of degradation, as well as with increasing size of the alkyl substituent. The threshold temperature of degradation of each polymer was calculated from the values of s/P-0. At lower degradation temperatures and times branching occurs in PDBI and PDHI and crosslinking in PDOI.

AB  - Starch esterification with benzoyl chloride was performed in two steps, the first being the alkali treatment of the starch and the second, esterification. Samples of hydrophobic starch benzoate were synthesized with degrees of substitution: 0.73.1.18 and 1.16 and their thermal stability was investigated by non-oxidative, non-isothermal thermogravimetry. It was shown that starch benzoate was thermally less stable than native starch, the thermal stability decreasing with increasing degree of substitution. The results indicated that the scission of CO2 and/or benzoyl groups probably occurred in the temperature region 100-260 degreesC, depending on the dear of substitution. The overall activation energies of thermal degradation were calculated by the Flynn-Wall method.

AB  - The radical polymerization of monoethyl itaconate (MEI) was investigated in bulk and in solution at 60°C using a,a'-azobisisobutyronitrile as initiator. It was established that the obtained polymer poly(monoethyl itaconate) was insoluble in its monomer, implying that the bulk polymerization of MEI was a precipitation polymerization. The polymerization kinetics of MEI were discussed and compared to the polymerization kinetics of structurally similar alkyl itaconates. The homogeneous radical polymerization of MEI in tetrahydrofuran was not possible in the whole range of monomer/solvent concentration ratios, while the polymerization of MEI in methanol was homogeneous. The chain transfer constants to THF and methanol at 60°C were determined.

AB  - The thermal stability of poly(methyl methacrylate) (PMMA) and silicon carbide (SiC) composites was studied by thermogravimetry. The influence of particle size, SiC structural modification and particle specific surface was analyzed. It was established that particle size had the greatest influence on PMMA/SiC thermal stability and that the most stable composites were those with the smallest particle diameter, i.e the largest particle specific surface. The values of the thermal degradation activation energy indicated that in some cases particle deagglomeration probably did occur which enabled polymer-filler nanoscale interaction and indicated that the system PMMA/SiC could form nanocomposites.

AB  - The goal of this investigation was to study the thermal degradation of poly(ditetrahydro-furfuryl itaconate) (PDTHFI) by thermogravimetry (TG). The monomer was polymerized in bulk at 40 degreesC using AIBN as initiator. Non-oxidative degradation was studied under nitrogen, while oxidative degradation was studied under air, applying four heating rates (2.5, 10, 20 and 40 K/min), up to 600 degreesC. The apparent activation energy of thermal degradation, E-a, was calculated using the Flynn-Wall method. The obtained non-oxidative TG curves of PDTHFI are parallel and no heating rate effect was observed. A carbonaceous residue remained at 600 degreesC, regardless of the heating rate applied. The E-a of PDTHFI is constant in the whole mass loss range and its mean value is 124 kJ/mol. The non-oxidative differential TG (DTG) curves of PDTHFI consist of two peaks, the second being dominant. If it is assumed that depolymerization is the main degradation mechanism, analogous to other polyitaconates, these two peaks could be ascribed to two depolymerization initiation modes: end-chain beta -scission and random main chain scission. The oxidative TG curves are more complex than the non-oxidative ones and show a heating rate effect. The E-a steadily increases in the mass loss range of 5-50% from 120 to 200 kJ/mol. The oxidative DTG curves consist of a major peak with two shoulders and a second minor peak.

AB  - The kinetics and mechanism of the thermal degradation of poly(diethyl tumarate) (PDEF) were studied by thermogravimetry and analysis of the polymer residue. The characteristic mass loss temperatures were determined, as were the overall thermal degradation activation energies of three PDEF samples of varying molar mass. The dependency of residual polymer molar mass on the degradation time and temperature was established and the kinetic chain lengths of depropagation, Z, and the number of main-chain scissions per monomer unit, s/Po, calculated. A thermal degradation mechanism including de-esterification, random main-chain scission, depolymerization and carbonization is proposed. The thermal degradation of PDEF is compared to the thermolysis of poly(methyl methacrylate) (PMMA) and poly(diethyl itaconate) (PDEI).

AB  - The non-oxidative thermal degradation of poly(iso-butyl methacrylate) and poly(sec-butyl methacrylate) was investigated by studying changes in the polymer residue. Due to the different number of β-hydrogens in their ester substituents, these two polymeric isomers behave differently when subjected to elevated temperatures. Poly(iso-butyl methacrylate) degrades quantitatively by depolymerisation with zip lengths of the same order of magnitude as those of poly(methyl methacrylate). Poly(sec-butyl methacrylate) degrades by a combined degradation mechanism of depolymerisation and de-esterification. De-esterification becomes a significant thermolysis route at temperatures higher than 240 ºC. .

AB  - The non-oxidative thermal degradation mechanism of poly(di-n-propyl-) (PDnPI) and poly(di-iso-propyl itaconate) (PDnPI) were investigated and compared to the structurally similar polymethacrylates. Analogous to the corresponding polymethacrylates, PDnPI thermally decomposes predominantly by depolymerisation, whereas a considerable amount of side chain scission occurs during the thermal degradation of PDiPI. The thus formed carboxyl groups decarboxylate at elevated temperatures forming a carbonaceous residue.

AB  - Monoesters of itaconic acid (monobutyl itaconate and monocyclohexyl itaconate) were synthesized and used as monomers. Poly(monobutyl itaconate) (PMBI) and poly(monocyclohexyl itaconate) (PMCHI) were prepared by free radical polymerization of these monomers using tert-butyl hydroperoxide as initiator. Subsequently, ABA type block copolymers where the A block is PMBI or PMCHI and the B block is poly(dimethyl siloxane) (PDMS) were synthesized by free radical polymerization using a macroinitiator (diperoxycarbamate) containing PDMS units. The structural formulae of the products were confirmed by spectral analysis. The molecular weights of the products are not high. Therefore the mechanical and physical properties are rather poor. However, porous structures of copolymers are observed by means of SEM.

AB  - Non-oxidative and oxidative thermogravimetry was performed on poly(di-n-propyl-) (PDnPI), poly(di-iso-propyl-) (PDiPI), poly(di-n-butyl-) (PDnBI), poly(di-iso-butyl-) (PDiBI) and poly(di-sec-butyl itaconate) (PDsBI). The results show that PDiPI and PDsBI thermally degrade in a similar manner with deesterification being, together with depolymerisation, a significant mechanism. PDnPI and PDnBI also degrade in a similar manner by depolymerisation, with chain end initiation being more important than random main chain scission initiation. The results for PDiBI indicate more similarity to the n-alkyl esters than to the other branched chain esters although, there are indications that also with this polymer ester decomposition is not an insignificant thermal degradation mechanism, although little can be said about the mechanism of oxidative thermal degradation of these polymers. the kinetic data again show the similarity between PDnPI and PDnBI on the one hand, and PDiPI and PDsBI on the other. Also, in an oxidative atmosphere, PDiBI shows more similarity to the n-alkyl esters than to PDiPI and PDsBI. It would appear that, as with the polymethacrylates, the number of beta-hydrogen atoms in the ester substituents plays a dominant role in determining the mechanism of both the thermal and thermo-oxidative degradation of these polymers.

AB  - Thermogravimtery (TG) is a convenient method for the routine, as well as non-standard characterisation of polymeric materials. The changes in wood under various heating condi­tions were followed and on the basis of the obtained results the thermal degradation activa­tion energies of several samples were determined. The TG of several softwood and hard­wood samples was performed, as well as of some beechwood components such as cellulose and hemicelluloses. The application of TG enabled the distinct differentiation of hardwood from softwood samples, while the differences within one group were less expressed.
