新颖、独特的聚烯烃合成方法新进展(下)

目前聚烯烃产品的全球产量已占热塑性塑料全球总产量的一半。但由于聚烯烃产品的结构中缺乏功能性基团,且用传统的配位聚合方法又难于引入极性基团,因此拓宽聚烯烃的应用领域就受到一定限制。回顾并阐述近年来出现的全新的烯烃聚合物的合成方法,包括:非环二烯易位聚合、碳烯聚合、催化链增长反应、点击反应和不用烷基铝的配位聚合的聚合方法及其反应原理。

Progress of Novel and Unique Olefin Polymerization Methods

Polyolefin production has accounted for more than half of thermoplastics production worldwide.Despite its commercial importance,the lack of functional groups in its structure and difficulty to introduce polar groups into traditional coordination polymer have significantly limited many end usages.Novel polymerization approaches have been developed in recent years.This article reviewed these unique polymerization methods,namely,acyclic diene metathesis polymerization,carbene polymerization,catalytic chain growth,click reaction,and coordination polymerization without aluminum alkyls.
