Abstract
A novel fluorine-containing copolymer having functional groups comprising structural units of 1,1-difluoroethylene and structural units of a monomeric compound of the formula: ##STR1## wherein X is --OH, ##STR2## or --COOH group, m is 0 or an integer of 1 to 10 and n is an integer of 1 to 4, which may futher contain structural units of at least one monomer selected from the group consisting of tetrafluoroethylene, chlorotrifluoroethylene, monofluoroethylene 1,1,2-trifluoroethylene, hexafluoropropene and a fluoroalkyl vinyl ether. The copolymer is curable at room temperature, and is useful as a material for fluorine-containing rubbers, molded articles and paints.
