| 摘 要： | 以苯乙烯（St）、γ-甲基丙烯酰氧丙基三甲氧基硅烷（TMSPMA）为单体，十二烷基硫酸钠和辛基酚聚氧乙烯醚为复合乳化剂，通过乳液聚合法制备了St-TMSPMA共聚物。用傅里叶变换红外光谱仪对共聚物进行了表征，1090 cm-1处Si－O－Si键的吸收峰和1723 cm-1处羰基的伸缩振动吸收峰表明TMSPMA与St发生了共聚反应；并研究了反应温度、引发剂浓度、乳化剂浓度和TMSPMA浓度对乳液共聚反应速率的影响，结果表明，升高反应温度、增大引发剂或乳化剂浓度以及降低TMSPMA浓度都可以提高聚合反应速率。

| Abstract: | The copolymer of styrene (St) and 3-(trimethoxysilyl)propyl methacrylate (TMSPMA) was synthesized via emulsion copolymerization using sodium dodecyl sulfate and octylphenol polyoxyethylene ether as emulsifiers. The effects of content of emulsifier, initiator, and TMSPMA as well as polymerization temperature on the polymerization rate were investigated in detail. The copolymerization between TMSPMA and St was confirmed by the appearance of absorption peaks at 1090 cm-1 (due to Si-O-Si bonds) and 1723 cm-1 (due to C=O bonds) in FT-IR spectrum. The polymerization rate increased with increasing polymerization temperature, molar concentration of emulsifier and initiator, but decreased with increasing molar concentration of TMSPMA. |
