FIELD: chemistry. ^ SUBSTANCE: invention relates to organic high-molecular compounds. The elastic fluorocopolymer contains a repeating unit (1) based on a fluoromonomer such as tetrafluoroethylene, hexaflouropropylene, vinylidene fluoride or CF2=CF-O-Rf (where Rf is a saturated C1-8 perfluoroalkyl group or perfluoro(alkoxyalkyl) group) and a repeating unit (m) based on formula CR1R2=CR3COOCH=CH2 (in which each of R1 and R2 is a hydrogen atom, C1-10-alkyl group or C1-10-alkoxyalkyl group, containing an oxygen atom of an ether, and R3 is a hydrogen atom, fluorine atom or methyl group) in molar ratio (m)/(1)=0.0001-0.1. The elastic fluorocopolymer mixture contains (A) the said elastic fluorocopolymer, (B) an unsaturated multifunctional compound and (C) an oxide and/or hydroxide of a bivalent metal. ^ EFFECT: elastic fluorocopolymer and elastic fluorocopolymer mixture have excellent crosslinking capacity and can make crosslinked rubber with excellent properties. ^ 16 cl, 4 tbl, 13 ex |
