摘要
非“活性”的端羧聚丁二烯及端羧聚丁腈胶通过THF开环聚合转变为双端正离子活性链。用液氨或二乙胺终止反应制得伯胺或叔胺端基遥爪聚丁二醇-聚烯烃-聚丁二醇三嵌段低聚物。
Carboxy end-capped polybutadine and butadine-acrylonitrile copolymer were transformed into dicationically living poly (THF-b-butadine-b-THF) and poly (THF-butadine-avryloni-trile-b-THF) triblock chains, respectively, through the ring-opening polymerization of THF. By terminating the reaction with liquid ammonia or diethylamine the telechelic triblock with primary or tertiarr amine end-groups, respectively, was synthesized. The tertiary amine terminated triblock oligomer reacted with a,a'-dic,hloro-p-xylene gives rise to the formation of thermoplastic elastomer ionene polymer.
