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.
Glicidil azid polimer (GAP), energetski, termički stabilni, nisko osetljivi, hidroksi terminirani polimer, sintetisan je korišćenjem različitih diola i triola kao inicijatora. GAP je pripremljen azidacijom poli(epihlorohidrina) (PECH) sa različitim poliolima u polimernom lancu. PECH je dobijen katjonskom polimerizacijom otvaranjem prstena, sa BF3-eteratom kao katalizatorom i poliolom kao ko-katalizatorom. Sintetisani polimeri su okarakterisani pomoću IR-spektroskopije, priroda hidroksi terminirane grupe je potvrđena protonskom NMR spektroskopijom. Određene su temperature staklastog prelaza (Tg) i osetljivosti na termičke impulse. Fizičko-hemijske i reološke osobine su potvrđene određivanjem: hidroksilnog broja, molarne mase, gustine i viskoznosti.
