<p>PURPOSE:A fluorine-contained copolymer useful as a cold curing coating compound having improved chemical resistance, weather resistance, antifouling properties, etc., containing a vinylidene fluoride structural unit, and a specific functional fluorovinylene structural unit. CONSTITUTION:The desired copolymer containing (A) a structural unit shown by the formula I , (B) one shown by the formula II (X is OH, group shown by the formula III, or -COOH; m is 1-10; n is 1-4 integer), and, if necessary, (C) one or more selected from the group consisting of the groups shown by the formula IV- formula IX (Rf is fluorine-containing alkyl group). USE:Useful as fluorine rubber by adding a monomer to reduce the glass transition temperature to the copolymer.</p> |
