A peroxidic fluoropolyether and its use in emulsion polymerization of fluorin-containing monomer

The present invention relates to a kind of a fluorinated polyether and peroxide also obtained by this polymerization of a fluorinated monomer by using a fluorine surface active agent dispersion. The fluorinated polyether peroxides can be used as a surface active agent to replace the octanoic acid or its salt in the manufacture of a number of components perfluoro dispersion of the fluorine monomer. Thus, it is possible to reduce the octanoic acid or a salt thereof The amount perfluoro to protect the natural environment. The fluorinated polyether surfactants peroxide is advantageous in controlling the polymerization reaction to proceed and the reaction derivation calm and smooth under the joint action of auxiliary initiators, reducing the amount of the initiator, it is possible to shorten the reaction time.
