Abstract
An elastic fluorocopolymer comprises repeating units (l) based on a fluoromonomer such as tetrafluoroethylene, hexafluoropropylene, vinylidene fluoride or CF═CF—O—R(wherein Ris a Csaturated perfluoroalkyl group or a perfluoro(alkoxyalkyl) group) and repeating units (m) based on the formula CRR═CRCOOCH═CH(wherein each of Rand Ris a hydrogen atom, a Calkyl group or a Calkoxyalkyl group containing an etheric oxygen atom, and Ris a hydrogen atom, a fluorine atom or a methyl group) in a molar ratio of (m)/((l)+(n))=0.0001 to 0.1. Further, an elastic fluorocopolymer composition comprises (A) the above elastic fluorocopolymer, (B) an unsaturated multifunctional compound and (C) a bivalent metal oxide and/or hydroxide. The elastic fluorocopolymer and the elastic fluorocopolymer composition are excellent in the crosslinkability and can provide a crosslinked rubber thereof excellent in crosslinked rubber properties.
