摘要： The invention relates to a curable fluorine-containing copolymer prepared by copolymerizing a monomer mixture. This monomer mixture is in an amount of 100 mol % in total and includes (a) 10-60 mol % of a first polymerizable monomer that is one of hexafluoroisobutene and hexafluoroacetone, each of which has one hexafluoroisopropylidene group; (b) 10-70 mol % of a fatty acid vinyl ester that is represented by a general formula of CH.sub.2 .dbd.CH--OC (.dbd.O) --R.sup.1 where R.sup.1 is one of an alkyl group and --(CH.sub.2).sub.m --R.sup.2 --(CH.sub.2).sub.n --H where R.sup.2 is one of a cycloalkylene group and a divalent aromatic group, and m and n are respectively integers each ranging from 0 to 12, the alkyl group having a carbon atom number of from 1 to 22 and an optional branched chain, each of the cycloalkylene group and the divalent aromatic group having an optional substituent; (c) 1-60 mol % of a second polymerizable monomer that has a cross-linkable functional group and a polymerizable double bond, the cross-linkable functional group being one selected from the group consisting of hydroxyl group, carboxyl group, hydrolyzable organosilyl groups, epoxy groups, .beta.-ketoester groups; and (d) 0-20 mol %, of a third polymerizable monomer that is different from the first and second monomers and the fatty acid vinyl ester and is free of a cross-linkable functional group. A coated film prepared by the application of a varnish containing the fluorine-containing copolymer is superior in water repellency and stain resistance.
