  一种含氟羧酸的制备方法

  摘要：

  本发明公开了一种含氟羧酸的制备方法，该方法是以含氟羧酸盐为原料、通过与酰氯化试剂反应得到相应的含氟酰氯和含氟酸酐的混合物、再将含氟酰氯和含氟酸酐的混合物水解干燥后制备高纯度含氟羧酸。本发明方法适用于含氟烯烃（单烯烃、二烯烃、环烯烃等）氧化法制备含氟羧酸的后处理，代替传统的强酸酸化和乙醚连续萃取工艺，更为简便适用；也可用于回收和纯化含氟羧酸盐类乳化剂。本发明制备的含氟羧酸纯度可达98%以上。

  Disclosed is a melt processible semicrystalline fluoropolymer comprising: (a) about 0.001 to about 25 weight percent of repeating units arising from a hydrocarbon monomer having a functional group and a polymerizable carbon-carbon double bond, wherein said functional group is at least one selected from the group consisting of amine, amide, hydroxyl, phosphonate, sulfonate, nitrile, boronate and epoxidehydrocarbon monomer; and (b) the remaining weight percent of repeating units arising from tetrafluoroethylene. This melt processible semicrystalline fluoropolymer is impermeable to fuels and is useful as a lining for petroleum fuel tubing, as well as chemical resistance coating for, or adhesive between, perfluoropolymer and other polymers, metals and inorganics.

  Disclosed is an aqueous polymerization process for the manufacture of a fluoropolymer comprising repeating units arising from a perfluoromonomer and a monomer having a functional group and a polymerizable carbon-carbon double bond, comprising: (A) combining water and a perfluoromonomer to form a reaction mixture; (B) initiating polymerization of the perfluoromonomer; (C) polymerizing a portion of the perfluoromonomer to form particles of polymerized perfluoromonomer in the reaction mixture; (D) adding to the reaction mixture a monomer having a functional group and a polymerizable carbon-carbon double bond; and (E) polymerizing the perfluoromonomer and the monomer having a functional group and a polymerizable carbon-carbon double bond in the presence of the particles of polymerized perfluoromonomer to form the fluoropolymer. The fluoropolymer is useful as an adhesive and coating.
