摘　　要：采用丙烯酸 -甲基丙烯酸正丁酯 -醋酸乙烯酯三元共聚的方法 ,合成了改性乳液 ,讨论了共聚单体、温度和乳化剂等的影响。实验结果表明 :改性后的共聚乳液 ,剪切强度、耐水性、抗冻性有较大的提高。In this paper,modification method of terpolymer of vinylacetate with acrylic acid and n-butyl methacrylate was introduced,and the effects of comonomer、 temperature and emulsifiers were discussed.Experimental results showed that terpolymer emulsion had higher shear strength and ability to resist water and freeze than the normal PVAc emulsion.
