摘　　要：采用乳液聚合法制备了N-羟甲基丙烯酰胺改性苯乙烯-丙烯酸酯乳液。研究了乳化剂的选择与用量、聚合温度、N-羟甲基丙烯酰胺的用量、功能单体的用量对苯丙乳液综合性能的影响。实验表明,当N-羟甲基丙烯酰胺为单体总质量的2%,功能单体为单体总质量的2%,m(十二烷基苯磺酸钠):m(乳化剂OS)=2:1时,以过硫酸铵为引发剂,在78～82℃反应4h可得到综合性能较好的苯丙乳液,其具有很好的成膜性和物理机械性能。The N-hydroxymethyloacrylamide modified styrene-acrylic emulsion was synthesized by emulsion polymerization. The effects of the selection and content of emulsifier, the polymerization temperature, the contene of N-hydroxymethyloacrylamide, content of the functional monomer on the styrene-acrylic emulsion were discussed. The results showed that the styrene-acrylic emulsion has excellent film-forming and mechanical properties when the N-hydroxymethyloacrylamide monomer total of 2% of the functional monomer to monomer 2% of the total, Sodium dodecylsulfate ： Emulsifier OS （mass ratio） of 2 ： 1, Ammoniumpersulfate as initiator, in 78 to 82 ℃ 4 h.
