Zusammenfassung: | The present invention is a fluorine-containing copolymer including (A) a fluoroolefin in an amount of 15 to 85 mol% of all constituent monomers; (B) a specific organosilicon compound in an amount of 0.001 to 10 mol% of all the constituent monomers;(C) one or more monomers selected from vinyl ethers, vinyl esters, methacrylic esters and acrylic esters, the one or more monomers not having a curing reactive group and having an aliphatic saturated hydrocarbon group with 1 to 20 carbons, a glass transition temperature of a homopolymer of the monomer being lower than 0°C, in an amount of 5 to 40 mol% of all the constituent monomers; and (D) one or more monomers selected from vinyl ethers, vinyl esters, allyl ethers, methacrylic esters and acrylic esters, and having a curing reactive group, in an amount of 1 to 25 mol% of all the constituent monomers, wherein the fluorine-containing copolymer has a glass transition temperature of -30°C to 20°C, a number average molecular weight of 2.0×104to 7.0×104, and a weight average molecular weight of 1.0×105to 3.0×105. |
