摘　　要：通过醋酸乙烯酯与其它烯类单体共聚,制备出一种新型改性聚醋酸乙烯酯乳液,不仅解决了聚醋酸乙烯酯乳液胶粘剂耐水性、抗冻性差的问题,而且满足环保要求。实验过程中利用TEM、DSC、旋转粘度计等测试方法分析讨论了共聚改性过程中乳液的组成对乳液性质的影响。In this research work,a new kind of modified polyvinyl acetate emulsion was synthesized by copolymerization of VAc and some other vinyl monomers.The lower waterproof and cold-thaw properties for PVAc traditional emulsion were improved and the new emulsion products met the requests in environmental protection.The effect of the emulsion composition in the copolymerization on the properties of the emulsion products was investigated with TEM,DSC and other analytical methods.
