摘　　要：在超声波的乳化作用下,研究了丁苯胶乳的核壳聚合反应,用透射电镜对胶乳粒子的粒径大小及其分布进行了表征。结果表明,当苯乙烯聚合80min、单体转化率达到73%时,所得到的核壳结构胶乳粒径在20nm左右,且具有单分散性。Much attention has been paid to the ultrasonic emulsification and the core-shell polymer and nanoparticles in recent years. There are more advantages over other emulsification by ultrasonic.In this research, nanoparticles latex with core-shell structure was prepared with seeded emulsion polymerization by ultrasonic emulsification.
