Abstract
Abstract A fluorine-containing copolymer comprising structural units of the formula (a): structural units of the formula (b): wherein n is an integer of 1 to 10 and structural units of the formula (c): wherein X is -H, -Cℓ or -F and Y is -F, a lower fluoroalkyl group or a group having the formula: in which m is 0 or an integer of 1 to 3 and a curable composition comprising the fluorine-containing copolymer and a curing agent. The fluorine-containing copolymer is compatible with acrylic resins and is excellent in transparency, and the composition can be employed as a room temperature curing paints material.
