[ 1 ] - بررسی اثر زنجیرافزاینده 4،4 َ- بیس(فنیل آمین) متان بر خواص مکانیکی و حرارتی شبکه‌ پلی‌اوره- یورتان بر پایه HTPB

Polyurea-urethanes are one of the polyurethane categories that causes better phase separation due to increasing the hard segment length and non-covalent interactions. In this research, hydroxyl-terminated polybutadiene based polyurea-urethanes have been synthesized via one-pot polymerization of triethanol amine triflouroborate comlex as cross-linker, isophoron diisocyanate as curing agent and v...
