摘要： 采用无皂乳液聚合方式，合成了醋酸乙烯酯／丙烯酸／丙烯酸丁酯（ＶＡｃ／ＡＡ／ＢＡ）三元共聚物，探讨了丙烯酸丁酯结构单元、引发剂用量、反应温度对乳液稳定性、黏度、转化率以及粘接强度的影响。结果表明：ＢＡ和过硫酸铵（ＡＰＳ）用量分别为混合单体总质量的 ８.０％、０.５％，反应温度为 ７５℃时，共聚乳液具有良好的性能。

Abstract: The copolymer of PVAc /MA/BA were prepared by emulsifier -free emulsion process. The in-fluence of structural unit of butyl acrylate initiator content and the reaction temperature on stability of emul-sion,viscosity, conversion rate and adhesive strength was studied. It was indicated that when BA and APS were 8. 0% and 0. 5% of the amount of mixed monomers respectively and reaction temperature of 75 C,the copolymer emulsion showed the best performance.
