摘　　要：马来酸酐与月桂醇反应合成了马来酸十二酯（1）,以1为反应型乳化剂制备了苯丙乳液（2和2′）。对2和2′的结构与性能进行了初步研究,探讨了聚合工艺、反应时间、单体转化率、温度等对2′性能的影响。制备2′的最佳反应条件为：w（1）=2.5%,用水量50%~60%,采用预乳化法,于75℃~80℃反应6 h,单体转化率96.2%。2′的最低成膜温度约22℃;0.5%2′溶液的表面张力27.9 nN.m-1。Maleic acid tauryl ester（1） was synthesised by the esterification of maleic anhydride with lauryl alcohol.Styrene acrylic emulsions（2 and 2′） was prepared using 1 as reactive emulsifier.The structure and properties of 2 and 2′ were investigated.The efficts of polymerization process,reaction time,monomer conversion rate and temperature on the properties of 2′ were also discussed.The optimum reaction conditions of preparation 2′ at 75 ℃~80 ℃ for 6 h by preemulsion method were as follows： w（1） of 2.5%,w（H2O） of 50%~60%.Monomer conversion ratio was 96.2% under the conditions.The minimum temperature of 2′ to form membranous was about 22 ℃.The surface tension of 0.5% 2′ aqueous solution was 27.9 nN·m-1.
