Patent ID: 7915361

Claim:
A fluorocopolymer curable composition comprising a fluorocopolymer, a compound having 2 or more Si—H groups within each molecule, a hydrosilylation reaction catalyst, said fluorocopolymer being fluid at room temperature and curable, being obtained from a monomer substantially consisting of a trifluorovinyl group-containing monomer, having a number average molecular weight of 500 to 20000, and having an unsaturated group at both ends of a trunk chain, the trifluorovinyl group-containing monomer being a fluorovinylether of the following general formula (I): CF 2 ═CF—O—R 1 (I) (wherein R 1 represents an alkyl group of 1 to 20 carbon atoms optionally having 4 or less of oxygen atoms and optionally substituted by a fluorine atom), and/or being a trifluorovinyl group-containing linear compound represented by the following general formula (IV) [provided, however, that said fluorovinylether of general formula (I) is excluded]: CF 2 ═CF—(O—R f 2 ) n —Y 2 (IV) (wherein Y 2 represents an alkyl group of 1 to 5 carbon atoms optionally substituted by fluorine, an alkoxy group of 1 to 5 carbon atoms optionally substituted by fluorine, or a halogen atom; R f 2 represents a straight-chain or branched-chain perfluoroalkylene group of 1 to 3 carbon atoms; n represents an integer of 0 to 5).
