    摘要: The invention provides a novel copolymer comprising 25-75 mol % of a fluoroolefin such as CTFE, 10-70 mol % of a vinyl or isopropenyl ester of fatty acid, such as finyl acetate or isopropenyl acetate, 3-40 mol % of a hydroxyl-containing allyl ether such as ethylene glycol monoallyl ether, and 0.1-20 mol % of a carboxyl-containing monomer such as finylacetic acid. This copolymer possesses favorable properties characteristic of fluoroesins, is soluble in various organic solvents and is curable at normal temperature by a polyisocyanate. Since the copolymer has carboxyl group, not only inorganic pigments but also organic pigments exhibit very good dispersibility in a solution of this copolymer in an organic solvent. The copolymer can be prepared by a single-stage reaction using a radical polymerization initiator.
