description The invention relates to a preparation method of a brush type fluorine-containing amphipathic segmented copolymer. 4,4'-azo(4-cyanpentanoic acid), acrylic acid, methoxy polyethylene glycol methacrylate, solvents for reaction, S-1-dodecyl-S-S'-(alpha,alpha''-dimethyl-alpha''-acetic acid) trithiocarbonate are used for preparing polyacrylic acid methoxy polyethylene glycol methacrylate; weighed materials of the 4,4'-azo(4-cyanpentanoic acid), the hexafluorobutyl acrylate, deionized water, aqueous alkali and the polyacrylic acid methoxy polyethylene glycol methacrylate are used for preparing the brush type fluorine-containing amphipathic segmented copolymer. The brush type fluorine-containing amphipathic segmented copolymer prepared by the preparation method has high surface activity, high heat stability, high chemical stability and high freeze-thaw stability. 本发明种刷型含氟两亲性嵌段共聚物的制备方法：利用4，4′-偶氮(4-氰基戊酸)、丙烯酸、聚乙二醇单甲醚甲基丙烯酸酯、反应用溶剂、S-1-十二烷基-S′-(α，α″-二甲基-α″-乙酸)三硫代碳酸酯制备得到聚丙烯酸聚乙二醇单甲醚甲基丙烯酸酯；利用称取的4，4′-偶氮(4-氰基戊酸)、丙烯酸六氟丁酯、去离子水、碱
