Abstract
Liquid hydrocarbon type Hydroxyl terminated polybutadine (HTPB) and the polar glycidyl azide polymer (GAP) are in-situ compatibilized relaying on the large difference in rate of reaction with toluenediisocyanate (TDI). Reaction of the slower GAP with TDI and than HTPB enabled formation of a macroscopically homogenous rubber. The material turned to be unbound GAP droplets in cured HTPB. We assume that this structure is formed by formation of an in-situ surface active agents like GAP-(HTPB)n (nâ¯â¥â¯1).262
