Patent ID: 8138271

Claim:
A crosslinkable composition comprising: a compound represented by the general formula (4): wherein X 1 s are the same or different and each is hydrogen atom or a monovalent organic group; R 1 is OR 3 — or —SR 3 , and R 3 is a hydrogen atom or a monovalent organic group; a compound represented by the general formula (5): wherein R 4 s are the same or different and each is hydrogen, atom or cyano group; a compound represented by the general formula (6): wherein X 2 s are the same or different and each is hydrogen atom or monovalent organic group; Z − is an anion derived from an acid; Y 1 is —H, —OH, —SH or —N + X 2 2 H.Z − (X 2 and Z − are as defined above), and (B) a nonperfluoro fluorine-containing elastomer being capable of crosslinking reaction with the compound (A), wherein the nonperfluoro fluorine-containing elastomer (B) is selected from the group consisting of (1) vinylidene fluoride/hexafluoropropylene copolymer, (2) vinylidene fluoride/tetrafluoroethylene/hexafluoropropylene copolymer, (3) tetrafluoroethylene/propylene copolymer, (4) hexafluoropropylene/ethylene copolymer, (5) tetrafluoroethylene/vinylidene fluoride/fluoro(alkyl vinyl ether) copolymer, and (6) chlorotrifluoroethylene/vinylidene fluoride/fluoro(alkyl vinyl ether) copolymer.
