摘　　要： 用甲基丙烯酸甲酯、丙烯酸丁酯、丙烯酸等原料合成丙烯酸酯乳液。然后采用乳液聚合在丙烯酸酯中引入聚四氟乙烯(PTFE),得到聚四氟乙烯改性丙烯酸酯复合乳液。研究了不同乳化剂、引发剂和聚合工艺等对产品性能的影响,得到优化的反应条件。实验结果表明聚该复合乳液具有核壳结构且性能优异。 A waterborne polyacrylate emulsion were prepared with methyl methacrylate, butyl acrylate and acrylic acid, which is then modified by polytetrafluoroethylene. The influence of emulsifier, initiator and polymerization technology on the properties of emulsion were studied and the optimum reaction conditions were found. The experimental results show that the modified polyaerylate hybrid emulsion have core -shell structure and the properties of the modified polyacrylate hybrid emulsion by polytetrafluoroethylene were better than that of polyacrylate emulsion.
