核-壳型有机硅改性丙烯酸酯乳液的研制

Study on Core-Shell Structure Organic Siloxane Modified Polyacrylate Emulsion

采用种子乳液聚合法 ,以BA为壳 ,MMA为核 ,MAA、HEMA和有机硅氧烷为官能性单体 ,合成了内硬外软的核 -壳型有机硅改性丙烯酸酯乳液。讨论了官能性单体、核 -壳单体结构、乳化剂。

A core-shell structure organic siloxane modified polyacrylate latex was prepared by seed emulsion polymerization.The effects of functional monomers such as organic siloxane,methylacrylic acid (MMA) and hydroxy- ethyl methylacrylic acid (HEMA),emulsifier and initiator on polymerization process and the performances of core-shell structure polymer have been discussed.
