摘　　要：以丙烯腈改性淀粉为分散剂,苯乙烯(St)、丙烯酸丁酯(BA)、甲基丙烯酸二甲基氨基乙酯(DM)为单体,丙烯酰胺(AM)为交联单体,环氧树脂(E-44)为功能单体,过硫酸钾(K2S2O8)为引发剂,采用无皂乳液聚合技术合成了一种阳离子苯丙乳液表面施胶剂,并对文化纸进行表面施胶。最佳合成工艺是:w(DM)=3%,m(St):m(BA)=3,w(AM)=4%,w(E-44)=0.3%,w(K2S2O8)=0.5%。The cationic surface sizing of styrene-acrylic polymers were synthesized by soap-free emulsion technology, using acrylonitrile modified starch as dispersant, dimethylaminoethyl methacrylate, styrene and butyl acrylate as monomers, acrylamide as cross-linking monomer, epoxy resin as functional monomer and potassium persulfat as initiator. Through testing the properties of the sizing papers, the optimum proportions are as follows： the amouts of DM being 3%, St：BA being 3, AM being 4%, E-44 being 0.3%, and amount of K2S2O8 being 0.596.
