摘要
借助于超声波振荡分散法,通过苯乙烯-二乙烯基苯-对氯甲基苯乙烯三元共聚合反应合成了可溶性聚苯乙烯微凝胶,用二乙基二硫代氨基甲酸钠(铜试剂)取代其中的氯原子得到具有Iniferter功能的多官能度自由基活性微凝胶,该活性微凝胶引发苯乙烯聚合得到星型高分子,星型高分子中仍有Iniferter功能的基团.
By the ultrasonic oscillation dispersion method, the soluble microgel of PS with chloromethylene was formed during copolymerization of styrene-divinylbenzene-p-chloro-methyl-styrene. When chlorine atoms in microgel were replaced by sodium N,N-diethyldithiocarbamate, the active microgel with iniferter function was obtained and it can be used to prepare the Star-Like PS initiated by ultraviolet radiation. Iniferter functional groups remained in Star-Like polymer.
