    Abstract: The present invention provides peroxidic fluoropolyether and a fluorin-containing dispersion obtained from polymerization of fluorin-containing monomers in the presence of peroxidic fluoropolyether as a surfactant. The peroxidic fluoropolyether can be used as surfactant for producing aqueous dispersion of fluorin-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.
