【摘要】 聚硅氧烷做乳液广泛应用于各种化妆品中。本文以八甲基环四硅氧烷为原料,采用阴离子开环乳液聚合的方法合成了稳定且接近于完全透明的聚二甲基硅氧烷阳离子型微乳液,通过动力学实验研究,结合文献推测了该聚合过程的反应机理,并利用透光度和光子相关谱法分析表征微乳液的粒径。更多还原

【Abstract】 Polysiloxane microemulsion had been used in all kinds of cosmetics.Some stable and approximatively trans- parent polydimethylsiloxane cationic microemulsions were synthesized by emulsion polymerization of octamethylcyclo tetrasiloxane anionic ring-opening reaction.With kinetics experimentation results,the basic reaction equations were devel- oped combining the literatures.The particle-size of the microemulison was characterized by transmittance analysis and photo corelation spectroscopy.更多还原
