ELASTOMERIC FLUOROCOPOLYMER, COMPOSITION CONTAINING THE SAME, AND CROSSLIKED RUBBERS |
(57) An elastic fluorocopolymer comprises repeating units (1) based on a fluoromonomer
such as tetrafluoroethylene, hexafluoropropylene, vinylidene fluoride or CF
2=CF-O-R
f (wherein R
f is a C
1-8 saturated perfluoroalkyl group or a perfluoro(alkoxyalkyl) group) and repeating units
(m) based on the formula CR
1R
2=CR
3COOCH=CH
2 (wherein each of R
1 and R
2 is a hydrogen atom, a C
1-10 alkyl group or a C
1-10 alkoxyalkyl group containing an etheric oxygen atom, and R
3 is a hydrogen atom, a fluorine atom or a methyl group) in a molar ratio of (m)/((l)
=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.
