摘要
本文由苯乙烯—对氯甲基苯乙烯—二乙烯基苯的三元共聚反应合成了聚苯乙烯微凝胶,通过铜试剂对氯的取代反应,得到了具有自由基引发活性的微凝胶;用其引发苯乙烯聚合得到星形聚苯乙烯。
The microgel of PS with chloromethylene was formed during cop-olymerization of styrene,p-chloromethylstyrene and p-divinylbenzeneWhen chloride atoms in microgel were replaced by sodium N,N-diet-hyldithiocarbamate,the radical active microgel was obtained and itcan be used for preparation of the star-like PS.
