摘要
概述了PVC主链中的结构缺陷,介绍了国内外原子转移自由基聚合和普通自由基共聚合的聚合机制及其主要技术特点,简述了改善PVC热稳定性的方法,指出对PVC具有应用前景的改性途径。
The structural defects in the main chain of PVC were described. The polymerization mechanism and main technological characteristics of atom transfer radical polymerization and that of common radical polymerization at home and abroad were introduced. Methods of improving the thermal stability of PVC were described briefly. The modification ways with application prospects for PVC were indicated.
