摘　　要：采用预乳化工艺及半连续种子聚合法,通过St-BA-MMA-AA四元共聚反应,制得了具有核壳结构的苯丙乳液。讨论了乳胶粒子大小及形态对MFT的影响,并研究了乳化剂用量、阴/非离子乳化剂配比、核壳两阶段乳化剂配比及功能性单体的用量及加入方式对乳液性能的影响。The styrene-acrylate polymer emulsion with core- shell structure is prepared by pre-emulsification process and semi - continuous seed polymerization with St, BA, MMA and AA. The effects of particles size and particle morphology on the minimum film forming temperature are discussed. The influences of the amount of emulsifier, the ratio of anionic emulsifier to nonionic emulsifier, the amount and introducing process of functional monomers and et al on the properties of the emulsion are also studied.
