摘要
以预乳化种子半连续乳液聚合法制备了阳离子型聚丙烯酸酯乳液。探讨了不同的乳化体系和聚合工艺对乳液性能的影响;功能性单体种类及功能性单体的添加方式对乳液聚合及乳液稳定性的影响。实验表明,采用种子半连续乳液聚合方法,以AIBA为引发剂,使用丙烯酸羟丙酯(HPA)为功能性单体,并以后滴加方式加入时,制得乳液性能较好。
The cationic acrylate emulsion with functional monomers was prepared by pre-emulsified semi-con- tinuous seeded emulsion polymerization method. The effects of emulsifier systems, initiator systems, fuetional mon- omers on the polymerization process and the stability of emulsion were investigated. The results showed that the emulsion exhibited suprior stability when using AIBA as the initiator and hydroxyropyl acrylate as the funetioal monomer.
