Abstract
The invention provides a copolymer of 25-75 mol % of chlorotrifluoroethylene, 10-70 mol % of a vinyl or isopropenyl ester of fatty acid and 3-75 mol % of a hydroxyl-containing allyl ether represented by CH.sub.2 .dbd.CH--CH.sub.2 --O--(CH.sub.2)--OH, where n is an integer from 3 to 8, and 0-40 mol % of optional monomer(s) such as, e.g., vinylacetic acid or an acrylate. The copolymer is soluble in various organic solvents and curable with a polyisocyanate or a melamine resin, and the cured copolymer is excellent in weatherability, water resistance, chemical resistance and abrasion resistance. The copolymer is suitable for use as a paint vehicle.
Claims10
A copolymer comprising:
- 25 to 75 mol % of first repeating units which originate from chlorotrifluoroethylene;
