摘要

可逆配位链转移催化体系由过渡金属催化剂和主族金属烷基化合物组成，聚合物链在两者间进行快速可逆的链转移反应实现了聚合物的分子量、分子量分布的可控，且能够得到具有不同拓扑结构及立体选择性的均聚物和共聚物。配位链转移聚合(CCTP)除具有传统的活性阴离子聚合的优点之外，更重要的是，其平均每个活性中心可产生多条聚合物链，中心金属利用率超过100%，且催化剂立体选择性强。本文简要介绍了双烯烃配位链转移聚合研究进展，包括CCTP的基本原理，双烯烃配位链转移均聚合、共聚合及链穿梭聚合方面的研究。

Abstract

Coordinative chain transfer polymerization (CCTP) involves the use of a single transition metal-based catalyst and a chain transfer agent (CTA). The heart of CCTP is the highly efficient

rapid and reversible chain transfer reaction between active transition metal-based propagating centers and CTA. In comparison with anionic polymerization

coordinative chain transfer polymerization (CCTP) enables the growth of several macromolecular chains per active species. Moreover

CCTP can additionally afford a stereoselective polymerization

leading to the stereoregular polymeric microstructures and architectures under living conditions. This paper briefly reviews recent major advances in CCTP of 1
