摘　　要：采用三步法合成了可聚合乳化剂马来酸单十六醇酯丙基磺酸钠。并用正交实验法优化了马来酸单十六醇酯合成工艺条件,结果表明反应的最佳条件为:催化剂质量分数1%,反应时间3.0 h,反应温度90℃,马来酸酐与十六醇的摩尔比1.1∶1。苯乙烯-丙烯酸丁酯细乳液聚合使用该乳化剂与传统乳化剂相比,在较低温度下(65℃)具有较高的转化率,且所得乳液具有较好的电解质稳定性,乳胶膜的耐水性也得到提高。A polymerizable emulsifier sodium maleic hemihexadecylester propylsulfonate was synthesized in three steps. The synthetic conditions were optimized with design. Results show that the mass fraction of catalyst is 1%, reaction time is 3.0 h, reaction temperature is 90 ℃, and the molar ratio of maleic anhydride and 1-hecadecanol is 1.1 ： 1. The polymerizable emulsifier is applied in the Styrene-Butyl Acrylate mini-emulsion polymerization system. Compared with conventional emulsion polymerization, high rate of conversion （at 65 ℃） is observed, meanwhile, electrolytic stability and water resistance of the synthesized emulsion are markedly improved.
