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,并对施胶纸张各种性能作了测试。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%,与国内某产品对比,施胶度提高了15%,环压强度提高了18%。The cationic surface sizings of styrene-acrylic polymers are 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 persulfate as initiator.Through testing the properties of the sizing papers,the optimum proportions are as follows：the amouts of DM 3%,St：BA 3,AM 4%,E-44 0.3%,and amount of K2S2O8 0.5%.The degree of sizing improves by 15% and the ring crush strength increases by 18% compared with a domestic product.
