ABSTRACT:
The invention provides a copolymer which comprises, as essential components, 25-75 mol % of a fluoroolefin such as CTFE, 10-70 mol % of a carboxylic acid vinyl ester, 3-75 mol % of a hydroxyl-containing allyl ether and 0.1-20 mol % of an unsaturated carboxylic acid having at least 6 carbon atoms in the molecule. The copolymer is soluble in various organic solvents and curable, e.g., with a blocked polyisocyanate or a modified melamine resin. The copolymer can be prepared by a suspension polymerization method in an aqueous medium and hence can be made very low in the contents of unreacted residual monomers. The copolymer is very suitable for use in electrodeposition paints.
