摘　　要：研完硅溶胶和铝溶胶分别存在下甲基丙烯酸甲脂(MMA)的无乳化剂乳液聚合。结果表明,当溶胶粒子的表面电荷与生成的聚合物末端电荷相反时,胶囊化效果明显。采用透射电镜(TEM)技术,电泳实验对此进行表征。同时还研究了胶囊化对体系稳定性的影响。The emulsifier-free emulsion polymerization of methyl methacrylate (MMA) was carriedout in the presence of silica sol and alumina sol, respectively. It has been found that the encapsulation proceeds satisfactorily when the inorganic particles and the end groups of the resulting polymer are charged oppositely. The encapsulation was verified by transmission EM (TEM) and electrophoresis. In addition, the effect of encapsulation on emulsion stability was studied
