| 摘 要： | 以甲基丙烯酰氧基丙基三甲氧基硅烷(MPS)-聚二甲基硅氧烷(PDMS)-六甲基二硅氧烷(HMDS)为大分子单体、以双子表面活性剂为共乳化剂,通过乳液聚合的方法合成出有机硅改性丙烯酸酯共聚物,并用1 H-NMR、FT-IR、X射线衍射光谱(XPS))以及原子力显微镜(AFM)等手段进行表征。研究表明,采用双子表面活性剂作为共乳化剂,有机硅含量可高达50%,远高于其它文献的报道。

| Abstract: | The latexes of polysiloxane and acrylate with methacryloxypropyl trimethoxysilane(MPS)-polydimethylsiloxane(PDMS)-hexamethyldisiloxane(HMDS) oligomer as macromonomer and gemini surfactant as co-emulsifier were prepared by emulsion copolymerization and characterized by 1HNMR,FT-IR,x-ray photoelectron spectroscopy(XPS) and atomic force microscopy(AFM).With Gemini surfactant as co-emulsifier in the system,the PDMS content in the system could reach to 50%,which was far higher than the other reported value. |
