摘要
基团转移聚合(Group Transfer Polymerization,GTP)作为一种新的加聚方式,由于具有室温下使极性单体快速聚合;得到预期分子量和窄分子量分布的聚合物;可进行活性聚合,制备嵌段共聚物,对合成丙烯酸酯类橡胶或热塑性弹性体极为有利;可合成带有功能性端基和遥爪的聚合物等优点,近几年来发展迅速。到目前为止。
This paper reports the results on group transfer polymerization (GTP) of methyl metha-crylate in THF with dimethylketene ethyl trimethylsilyl acetal (ETS) as initiator and Et4NHF2 as catalyst. The dependence of the polymerization rates, molecular weights and polydispersity on the catalyst concentration has been studied. The living character of GTP is presented.
