烯烃配位-插入活性聚合催化剂的研究进展

Advances of Coordination-Insertion Living Polymerization Catalysts for Olefins

采用Ziegler-Natta催化剂进行烯烃配位-插入活性聚合近几年取得了很大的进展,已逐渐发展成为合成具有新型结构聚合物的有力工具,借助这种方法制备出从简单的均聚物(如线型或支化的聚乙烯和间规或等规聚丙烯)到各种嵌段共聚物和链末端带各种功能化基团的聚合物。系统综述了烯烃配位-插入活性聚合催化剂的研究进展(涉及到有机金属化学、高分子化学和材料科学);重点介绍了配体、催化剂的设计和活性聚合得到聚合物的性能。

In the last half decade, living coordination-insertion polymerization of olefins over ZieglerNatta catalyst has emerged as a powerful tool for synthesis of advanced polymers with new structures. Materials prepared by this method ranged from simple homopolymers, such as linear, branched, isotactic or syndiotactic polypropylenes, to various kinds of block copolymers and end-functionalized polymers. This review summarized recent developments in this rapidly growing research area, covering the fields of organometallic chemistry, polymer chemistry and material science. Special emphasis was concentrated on ligand and catalyst design, as well as the polymer properties prepared by such living polymerization.
