摘　　要：分别采用一次加料法和单体连续滴加法制备了含氢聚甲基硅氧烷 /醋酸乙烯酯 /羟甲基丙烯酰胺复合乳液 ,讨论了这两种聚合方法对乳液性能、粒径大小及转化率的影响 ,同时也考察了乳化剂配比及用量对乳液各项性能的影响。结果表明 :在单体连续滴加法下 。PHMS/VAc composite emulsion was synthesized,the effect of polymerization method on the stability of polymerization process,polymerization kinetic and other properties of emulsion was discussed.At the same time,emulsifier formula and amount on particle size,viscosity,surface tension and storage stability was studied.The results indicated that using composite emulsifier of non ionic emulsifier and anionic emulsifier properly could improve the properties of emulsion.The effect of polymerization method on properties of emulsion is important.
