  • Preparation method and use for fluorine-containing microemulsion
    Patent number: 9101892
    Abstract: A microemulsion consisting of water, peroxidic fluoropolyether carboxylate and oil is provided. When the microemulsion is used in homopolymerization, binary copolymerization or multi-component copolymerization of fluorine-containing olefin monomers, an emulsion with a low viscosity and a particle diameter of 30-200 nm can be obtained.
    Type: Grant
    Filed: December 30, 2010
    Date of Patent: August 11, 2015
    Assignee: ZHONGHAO CHENGUANG RESEARCH INSTITUTE OF CHEMICAL INDUSTRY CO., LTD
    Inventors: Jianxin Zhang, Xianquan Hu, Jiong He, Rong Bai
  • Peroxidic fluoropolyether and its use in emulsion polymerization of fluorin-containing monomer
    Patent number: 8536269
    Abstract: The present invention provides peroxidic fluoropolyether and a fluorine-containing dispersion obtained from polymerization of fluorine-containing monomers in the presence of peroxidic fluoropolyether as a surfactant. The peroxidic fluoropolyether can be used as surfactant for producing aqueous dispersion of fluorine-containing monomer in place of PFOA or the salts thereof. Thus the amount of PFOA or the salts thereof is reduced and the natural environment is protected. In addition, applying peroxidic fluoropolyether as surfactant and combining it with adjuvants, such as initiator, can induce the reaction moderate and can be beneficial to the polymerization control, thus reducing the amount of initiator or shortening the reaction time.
