摘　　要：利用无皂乳液聚合技术通过玉米/木薯淀粉和苯乙烯、丙烯酸丁酯等乙烯基单体进行接枝共聚反应,制备了一种稳定的淀粉接枝聚合物乳液,并研究了其对纸张的表面施胶性能。结果表明:利用玉米淀粉接枝乳液与玉米氧化淀粉复配,硫酸铝加入量为0.4%,施胶液pH值为4时,其应用效果最好。利用SEM观察了施胶前后纸张表面的微观结构。The graft copolymer of corn/cassava starch, styrene and butyl acrylate was produced in acidic media by soap-free emulsion polymerization and it＇s sizability was studied. The results showed that the best performance could be achieved when 10% of corn graft copolymer was added to oxidized starch, addition amount of Al2（SO4）3 was 0.4%, and pH value of sizing agent was 4. The microstructure of the surface of the paper before and after sizing was investigated by SEM.
