  • (a) fluorochemical monomer,(b) crosslinkable monomers, andC () be crosslinkable monomers not,Wherein said monomer (a), (b) and (c) are polymerized, thus produce described fluoropolymer under the existence of chain-transfer agent,Described fluoropolymer is 500 to 3000Pa-s at the complex viscosity of 70 DEG C,Described fluorochemical monomer (a) has following general formula;

    CH 2

    C(-X)-C(=

    O)-Y-Z-Rf(1) Wherein X is hydrogen atom, the alkyl with 1 to 21 carbon atom, fluorine atom, chlorine atom, bromine atoms, atomic iodine, CFX 1x 2base, cyano group, the fluoroalkyl with the straight or branched of 1 to 21 carbon atom, substituted or unsubstituted benzyl or substituted or unsubstituted phenyl, wherein X 1and X 2hydrogen atom, fluorine atom, chlorine atom, bromine atoms or atomic iodine;

    Y is-O-or-NH-;

    Z has the aliphatic group of 1 to 10 carbon atom, the aryl with 6 to 18 carbon atoms or alicyclic group or-CH 2cH (OZ 1) CH 2-Ji, wherein Z 1hydrogen atom or ethanoyl;

    And Rf is the fluoroalkyl of the straight or branched with 1 to 21 carbon atom,Described crosslinkable monomers (b) being has the monomer of epoxy group(ing) and has the combination of monomer of hydroxyl, the wherein said crosslinkable monomers with epoxy group(ing) is (methyl) glycidyl acrylate, and described in there is hydroxyl crosslinkable monomers be selected from least one in N-methylol-(methyl) acrylamide, (methyl) dihydroxypropyl methyl esters, (methyl) Hydroxyethyl Acrylate, (methyl) vinylformic acid 3-chlorine-2-hydroxyl propyl ester and (methyl) glycerol acrylate, andDescribed not crosslinkable monomers (c) is the acrylate of following general formula;
