Abstract
Different molecular weight glycidyl azide polymers without hydroxyl groups (GAP-azide) were prepared from commercial polyepichlorohydrin (PECH). Epichlorohydrin polymers have to be transformed into tosylate derivatives before azidation. GAP-azide samples were obtained by azidation of these PECH derivatives in N, N-dimethylformamide (DMF). Hydroxyl equivalent weights M sub e were determined by proton nuclear magnetic resonance (1 HNMR) to ensure that azidation was complete. Heats of combustion and glass transition temperatures were measured with a Parr bomb calorimeter and a Perkin-Elmer differential scanning calorimeter respectively.
