以含氟共聚物为助乳化剂的种子乳液聚合及其制备方法,属于化工高分子材料领域。利用含氟共聚物为助稳定剂的种子乳液聚合制备含氟丙烯酸乳液减少了含氟单体的消耗。先将含氟单体和乙烯基类单体或丙烯酸类单体通过自由基聚合合成共聚物;以含氟共聚物作为助稳定剂,采用种子乳液聚合法,合成出含氟丙烯酸乳液。该发明获得的含氟乳液不仅保留了聚丙烯酸乳液良好的成膜性、附着力、保光保 The fluorinated copolymer as a co-emulsifier for seed emulsion polymerization and a preparation method thereof belongs to the field of chemical polymer materials. Preparation of a fluorinated acrylic emulsion using seed emulsion polymerization of a fluorocopolymer as a co-stabilizer reduces fluoromonomer consumption. Firstly, the fluorinated monomer and the vinyl monomer or the acrylic monomer are synthesized by free radical polymerization to prepare the copolymer; the fluorinated copolymer is used as the stabilizer and the fluorine-containing acrylic emulsion is synthesized by seed emulsion polymerization. The fluorinated emulsion obtained by the invention not only retains the good film-forming property and the adhesion of the polyacrylic acid emulsion,
