ELASTIC FLUOROCOPOLYMER, MIXTURE THEREOF AND CROSSLINKED RUBBER Russian patent published in 2010 - IPC C08F214/18 

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-R^f (where R^f is a saturated C_1-8 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, C_1-10-alkyl group or C_1-10-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.
