PURPOSE:A crosslinkable fluorine-containing copolymer, containing vinyl units, specific hexafluorobutane units and fluorovinyl units, and having improved solubility in solvents. CONSTITUTION:A fluorine-containing copolymer containing structure units of formulas I , II and III (X is H or F; Y is -OH-, -COOH or group of formula IV; lis 0 or 1; m is an integer 0-6; n is an integer 1-3). A curable composition is obtained by adding a curing agent to the aimed copolymer containing 20- 70mol% structual units of formula I , 20-70mol% structural units of formula IIand 0.5-30mol% structural units of formula III. |
