摘要

由于具有较强的氧化性

超常价态过渡金属阳离子可与某些弱还原性基团构成氧化还原引发体系

引发自由基聚合。本文首先介绍了常见的几种超常价态过渡金属阳离子的电子构型以及其配合物结构

然后总结了超常价态过渡金属配合物与酰胺、醇羟基构成的氧化还原体系的引发机理

最后介绍了利用超常价态过渡金属配合物构成的氧化还原引发过程在制备接枝共聚物、嵌段共聚物、超支化聚合物以及星形聚合物方面的应用。

Abstract

Due to the strong o xidizing ability

supernormal-valence transitionmetal cations could form redox initiat ing systems with various reducing agents for the radical polymerization. This review covers (1) the electronic config uration and complex structure of commonly used superno rmal-valence transition metal cations; (2) the redox initiatiation mechanism of supernormal-valence transition metal cations with amides and alcohols; (3)the tailor-made synthesis of graft

block

hyperbranched and star-shaped polymers based on the supernormal-valence transition metal cations-catalyzed redox initiation.
