Transmission Electron Microscope and other properties testing results show that the complex emulsifier system is the crucial influence factor of the polymerization process and the properties of products. It may influence the coagulum content and reaction rate of the polymerization process, the performance, particle diameter,viscosity, electrolyte stability and storage stability of the emulsion products and the contact angle of the film.The initiator mainly influences the coagulum content and reaction rate.The acrylic monomers mainly influence the solid content, Minimum Film Formation Temperature of the emulsion and the Glass Transition Temperature of the film.The organic silicone monomer mainly influences the water absorption of the film.The reaction temperature mainly influences the reaction rate and conversion.The stirring intensity mainly influences the coagulum content of the polymerization process.

透射电镜等性能测试结果显示：复合乳化剂体系是硅丙共聚乳液的聚合过程及产品性能的主要影响因素，它可以对聚合过程的凝胶率、反应速率以及乳液的外观、粒径、粘度、耐电解质稳定性及贮存稳定性，还有乳液涂膜的接触角等造成不同程度的影响；引发剂主要影响反应速率和凝胶率；丙烯酸酯单体主要影响到乳液的固含量、最低成膜温度以及涂膜的玻璃化转变温度，有机硅单体主要影响涂膜的吸水率等；聚合反应温度主要影响乳液的反应速率和转化率等；搅拌强度主要是影响到聚合过程的凝胶率。

More levels of nano-SiO〓 lead to larger particle size. An increase in polymerization reaction temperature causes the decrease in coagulum and increase in viscosity and particle size, and the nano-SiO〓 has same effects at certain temperature. When the levels of hydrophilic monomer acrylic acid and hydroxylethyl methacrylate in core composite are increased, the particle size of emulsifier-free emulsion decreases, in spite of the presence of nano-SiO〓.

无皂乳液具有单分散性好、表面洁净、成本低廉、不影响产品性能的特点，首次研究了含或不含纳米粒子的含羟基和羧基的丙烯酸无皂乳液聚合，发现含或不含纳米粒子的无皂乳液聚合后的粒子粒径较大，具有单分散性；较多的纳米粒子导致较大的乳液粒径；反应温度升高，凝聚物含量下降，而乳液粘度和乳胶粒粒径增加，在相同的反应温度下，纳米粒子降低了聚合过程中的凝聚物含量，增加了乳液聚合物的粘度和粒径；不论纳米粒子是否存在，当无皂乳液核组成中亲水单体AA和HEMA用量增加时，乳胶粒粒径均减少。
