摘要
由双羟基聚丁二烯与聚乙二醇用甲苯二异氰酸酯偶联而成的多嵌段共聚物经萃取精制后用IR、GPC、元素分析、膜渗透压、X-射线衍射及透射电子显微镜等表征,并研究其不同组成与乳化性质、相转移催化性质及力学性能的关系.
Multiblock copolymers of butadiene and ethylene oxide prepared by coupling of telechetic hydroxyl polybutadiene and polyethylene glycol with toluene diisocyanate were purified, characterized and their emulsifying, phase transfer catalytic and mechanical properties were studied.
