Patent ID: 7538170

Claim:
A fluorocopolymer which is fluid at room temperature and curable, and which is obtained from a monomer composition consisting of trifluorovinyl group-containing monomers, has a number average molecular weight of 500 to 20000, and has a cure site at both ends of a trunk chain, said trifluorovinyl group-containing monomers comprise tetrafluoroethylene and a fluorovinylether represented by the following general formula (I): (wherein R 1 represents an alkyl group of 1 to 20 carbon atoms optionally having 4 or less of oxygen atoms and optionally being substituted by a fluorine atom) said cure site is a carboxyl group, an ester bond, a cyano group, a hydroxyl group, an unsaturated group, and/or a hydrolysable silyl group.
