Recent Advances of Some Novel and Unique Synthetic Methods for Polyolefins

聚烯烃产品的全球产量目前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,因此聚烯烃的应用领域仍受到一定限制。回顾并阐述了近年来出现的不少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。

Polyolefins have accounted for more than half of the world production of thermoplastics. Despite their commercial importance, the lack of functional groups in their structure and difficulty for the introduction of polar groups to traditional coordination polymer has significantly limited many end uses. New synthetic approaches have been developed in recent years. This article summarizes and reviews these various preparation methods, namely, acyclic diene metathesis polymerization, carbene polymerization, catalytic chain growth, click reaction and coordination polymerization without the use of aluminium alkyls.
