通过氟硅大单体与小分子乙烯基单体的自由基共聚，有望获得含氟硅的梳形接枝共聚物。以十二烷基硫酸钠（SDS）为乳化剂，正十六烷（HD）为助乳化剂，偶氮二异丁腈（AIBN）为引发剂，进行了甲基丙烯酸甲酯（MMA）与氟硅大分子单体（V - PMTFPS）的细乳液共聚反应研究。详细考察了共聚反应温度、引发剂浓度、乳化剂与助乳化剂用量等因素对 MMA 转化率的影响，并利用核磁共振氢谱（1 H - NMR）、示差扫描量热分析（DSC）等方法对共聚反应产物进行了表征。结果表明，MMA 可与 V - PMTFPS 很好地共聚，且转化率较高，获得了有机硅接枝型共聚物，可为利用大单体技术制备含氟硅共聚物材料提供依据。

Fluorosilicone-containing comb-like graft copolymers may be obtained by the radical copolymer-ization of fluorosilicone macromonomer with vinyl monomers. By using sodium dodecyl sulfate(SDS)as the surfactant,hexadecane(HD)as the co-stabilizer,and 2,2'-azobis(isobutyronitrile)(AIBN)as the initiator,this paper studies the miniemulsion copolymerization of methyl methacrylate(MMA)with vinyl-terminated poly[methyl(3,3,3- trifluoropropyl)siloxane](V-PMTFPS). It investigates the effects of pol-ymerization temperature,amount of surfactant,co-stabilizer and the initiator on the conversion of MMA. The composition and thermal properties of the obtained copolymers are also characterized by proton-nucle-ar magnetic resonance( 1 H-NMR)analysis and differential scanning calorimetry(DSC). The results show that MMA can be copolymerized well with V-PMTFPS,leading to high yields of graft copolymers. This study may be used as a basis for the preparation of fluorosilicone-containing copolymer materials with macromonomer technique.
