    Abstract: A rapidly curable fluorocopolymer comprises (a) 40 to 60 mole % of fluoroolefin units, (b) 8 to 60 mole % of the monovinyl ether of cyclohexanedimethanol units and (c) 5 to 45 mole % of alkyl vinyl ether units, wherein the mole % of a =b +c. The vinyl ether group provides an enhanced polymer Tg and a primary hydroxy site in the backbone of the polymer for effective and rapid crosslinking upon curing with isocyanates. The presence of (b) +(c) in substantially equimolar amounts with (a) provides coatings having the desired hardness without brittleness, and in suitable ratio for reaction copolymerization with (a).
