摘　　要：采用单体预乳化聚合法,以苯乙烯(St)、甲基丙烯酸甲酯(MMA)、丙烯酸丁酯(BA)、丙烯酸(AA)为单体,制备了苯丙微乳液,研究了合成温度、引发剂浓度等反应条件对苯丙乳液性能的影响。研究结果表明:当引发剂浓度为单体质量的0.7%,软硬单体的质量比为4∶6时,反应温度为85℃时,苯丙微乳液的综合性能良好。Styrene / acrylatemicro- emulsion was prepared by pre- emulsification method with styrene（ St）,methylmethacrylate（ MMA）,butyl acrylate（ BA） and acrylics acid（ AA） as the monomers. The reaction conditions such as reaction temperature and initiator dosage on the performance of as- synthesized styrene acrylic emulsion were systematically studied. The results showed that the styrene / acrylate micro- emulsion with higher solid content had good combination property when mass fractions of initiator was 0. 7%,mass ratio of m（ BA） ∶m（ MMA ＋ St） was 4∶6 and the reaction temperature was 85 ℃.
