摘要: 接枝共聚物含有性质差别很大的主链和支链,具有许多特殊的性质,因而一直是人们感兴趣的研究课题之一[1~5].原子转移自由基聚合(ATRP)[6,7]的问世,为接枝共聚物的合成提供了一条新的途径.本文用对-氯甲基苯乙烯和其它乙烯基单体自由基共聚.

Abstract: Aseries of graft copolymers were synthesized by ATRP initiated with macroinitiators which had been made from copolymerization of p-chloromethylstyrene and other monomers, such as methyl methacrylate, butyl methacrylate, acrylonitrile, styrene, vinyl acetate, isobutene-maleic anhydride, styrene-maleic anhydride etc.. The graft copolymers were characterized by IRand 1HNMR spectra. The numbers of graft points or the branches on the graft copolymers were determined by Ion Chromatography. The design for the various structures and architectures of the graft copolymers was made by changing the compositions of the backbones and the branches. The results indicated that it is a versatile route to synthesize a lot of graft copolymers and will be commercially important in the future.

Key words: p-Chloromethylstyrene, Macroinitiator, ATRP, Graft-copolymer
