AB  - Two types of alumina particles, commercial (c-Al2O3) and iron doped (Fe-Al2O3), were functionalized with 3-(aminopropyl)trimethoxysilane (one-step) and two-step consecutive process, i.e. firstly using 3-(aminopropyl)trimethoxysilane followed by methyl ester of linseed oil (biodiesel) to produce Al(2)O(3)ATPMS-BD reinforcement, respectively. The effect of modifier type and variable amount of alumina particles on the dynamical and mechanical properties of unsaturated polyester resin-based composites was studied. The highest improvement of the tensile strength and micro Vickers hardness, 78.1 and 163%, respectively, was obtained at 1.0 wt% of Fe-Al(2)O(3)APTMS-BD addition. The obtained multifunctional composites can be potentially applied in construction and mining industries.

AB  - Presented study was aimed to investigate the influence of surface functionalization of the industrial kraft lignin (KL) on mechanical and thermal properties of high-performance and fireproof composites based on unsaturated polyester (UPe) resin. In order to improve flame retardant properties, surface of the KL was modified by phosphorylation method in two-step process. First, direct grafting of phosphorus chloride on KL phenolic hydroxyl groups was performed and phosphoric acid ester of KL was formed. In the second step, phosphor ester of KL was recovered by precipitation in cooled isopropyl alcohol and the final obtained product, phosphorylated industrial kraft lignin with methyl terminal groups (KLP) was obtained. KLP mass contents in UPe based composites varied from 0.5 wt.% to 5.0 wt.%. Structural characterization was done via Fourier Transform-Infrared Spectroscopy (FT-IR). The effects of KLP surface functionalization and KLP mass contents on the UPe tensile properties were studied. Tensile strength (σ), elongation (ε) and Young's modulus of elasticity (E) and Shore A (Sh A) hardness of the UPe/KLP composites were analyzed in relation to the structure of KLP modification. Tensile testing results showed an increase in σ of 31 % for UPe/KL sample with 1.0 wt.% KL particles compared to the bare UPe matrix. The origin and cause of fracture that occurred during uniaxial tensile testing were analyzed using stereo microscopy. The obtained composites were tested on fire retardant properties in accordance with the standard test method UL-94V, and composites with 5.0 wt.% loaded KLP achieved V-1 category.
AB  - U radu su prikazani rezultati ispitivanja mogućnosti primene fosfatnih estara kraft lignina kao usporivača gorivosti u polimernim kompozitnim materijalima baziranim na nezasićenim poliestеrskim smolama. Sinteza fosfatnih estara lignina (funkcionalizacija lignina) izvršena je direktnim graftovanjem fosforoksihlorida na slobodne polifenolne grupe iz lignina, i potom hidrolizom hloridnih grupa izopropil alkoholom. Maseni sadržaj čistog i funkcionalizovanog lignina u poliestеrskim smolama variran je od 0,5 mas. % do 5,0 mas. %. Strukturna karakterizacija funkcionalizovanog kraft lignina i kompozita izvršena je primenom FT-IR spektroskopije. Proučavan je uticaj funkcionalizacije i masenog udela kraft lignina na tvrdoću, zatezna i termička svojstva nezasićenih poliestеrskih smola. Rezultati ispitivanja jednoosnog istezanja pokazali su da je povećanje zatezne čvrstoće od 31 % postignuto ugradnjom 1,0 % nefunkcionalizovanih čestica kraft lignina. Mehanizam nastajanja loma prilikom jednoosnog istezanja analiziran je primeneom stereomikroskopije. Termička svojstva kompozita analizirana su prema standardnoj metodi UL-94 na osnovu koje je kompozit sa 5,0 mas. % funkcionalizovanog lignina svrstan u najvišu kategoriju termootpornih materijala, V-1, a da su zatezna svojstva i tvrdoća po Šoru (eng. Shore A) ostala zadovoljavajuća.

AB  - The glycidyl azide polymer (GAP), known as an energetic, thermally stable, low sensitive, hydroxyl-terminated prepolymer, was synthesized using different diol and triol initiator units. GAP was prepared by azidation of poly(epichlorohydrin) (PECH) with different polyol units in the polymer chain. PECH was obtained by cationic ring-opening polymerization of epichlorohydrin, with BF3-etherate as a catalyst and polyol as a co-catalyst. The synthesized polymers have been characterized using IR-spectroscopy, while the prepolymers structure was confirmed by proton NMR spectroscopy. Additionally, glass transition temperature (Tg) and sensitivity to thermal stimuli were determined. Physico-chemical and rheological performances were carried out towards: end groups analysis, as well as density and molecular mass determination.

AB  - A possibility of using inorganic fullerene-like tungsten disulfide, IF-WS2, nanoparticles as a filler in poly (vinyl butyral), PVB, for improving its thermal and rheological properties is examined. PVB is a thermoplastic polymer with excellent properties, widely used: in ballistic protection, for protection of safety glass, in metal primers and coatings, temporary binders. Two different molecular weights of PVB were previously examined in this research: Mowital B60H and B75H. Both grades of PVB were dissolved in different solvents: ethanol and 2-propanol. Thin films were prepared by solvent casting technique. The glass transition temperature (Tg) of the tested samples was determined using differential scanning calorimetry (DSC), at three different heating rates (5°C/min, 10°C/min and 20°C/min). After choosing a solvent and PVB grade, IF-WS2 nanoparticles were added to PVB solutions and dispersed by ultrasonic irradiation. Compatibility, i.e. interaction of IF-WS2 with the dissolved PVB was examined by microcalorimetry method. The nanoparticles dispersion and deagglomeration in matrix of PVB was analyzed by scanning electron microscope (SEM). The effect of IF-WS2 on rheological properties of the chosen samples has been examined using Dynamic Mechanical Thermal Analysis (DMTA), observing storage modulus, loss modulus and the loss factor as functions of temperature for the tested composites.
