以丙烯酸酯、乙烯基三乙氧基硅烷(A151)为单体,采用复合乳化剂合成了有机硅改性丙烯酸酯纳米乳液.研究了有机硅、乳化剂、引发剂、反应温度及功能性单体甲基丙烯酸.2.羟基乙基酯(HEMA)、甲基丙烯酸(MAA)对乳液聚合反应速率的影响.结果表明,纳米硅丙乳液的聚合速率随乳化剂、引发剂、HEMA和MAA质量百分数的增加及反应温度的升高而增大,但随A151质量百分数的增大而减小.纳米硅丙乳液的聚合速率尺p与乳化剂浓度CE、引发剂浓度CI、A151浓度CA151、HEMA浓度CH、MAA浓度CM的关系为Rp=kCE0.2757CI0.1446CA151-0.3672CH0.0941CM0.0576.转化率在20%～80%范围内为恒定速率区,该区聚合反应的表现活化能为42.90 kJ/mol.
