摘　　要：利用功能单体马来酸酐、甲基丙烯酸羟乙酯改性苯丙乳液,苯乙烯、甲基丙烯酸甲酯、丙烯酸乙酯为主单体,分别合成聚苯乙烯-甲基丙烯酸甲酯-丙烯酸乙酯-马来酸酐(PSMEM)、聚苯乙烯-甲基丙烯酸甲酯-丙烯酸乙酯-甲基丙烯酸羟乙酯(PSMEH)聚合物表面施胶剂。应用表明:选择纸样烘干后70%乳液涂布法进行施胶对纸张的物理性质作用效果最优;PSMEH对纸张湿强度的影响优于PSMEM;PSMEH、PSMEM可使纸张具有很好的憎水性。By using functional monomer maleic anhydride, modified hydroxy-ethyl methacrylate emulsion, and taking styrene, methyl methacrylate, ethyl acrylate as main monomers, polystyrene-methyl methacrylate-ethyl acrylate-maleic anhydride （PSMEM）, polystyrene-methyl methacrylate-ethyl acrylate-hydroxy-ethyl methacrylate （PSMEH） polymer surface sizing agent has been synthesized respectively. Application results indicate that after dried, and sized with the 70% emulsion on the paper surface, the testing paper reached the best physical properties; PSMEH was superior to PSMEM in wet strength of the paper. PSMEH and PSMEM both made the oaoer Rood hvdronhobicitv.
