Study on Polyurethanes Based on Liquid Crystalline Diol

Liquid crystalline diol, terephthaloyl dioxydibenzonic acid butanediol ester (TOBB), wassynthesized, and it alone or with hydroxy-terminated POlybutadiene (HTPB) reacted with diisocyanatesto form liquid crystalline Polyurethanes. By using IR, DSC, polariz
