VINYLIDENE FLUORIDE-BASED BROMINE-CONTAINING COPOLYMERS FOR THERMO-AGGRESSIVE RESISTANT MATERIALS Russian patent published in 2010 - IPC C08F214/22 C08L27/16 C08F2/22 C08F4/40 C08J3/24

Abstract RU 2407753 C2

FIELD: chemistry.

SUBSTANCE: described are vinylidene fluoride-based bromine-containing copolymers of general formula -[CF₂R]_n-[CF(R_F) CF₂]_m-[CF(CF₂O(CF₂)KCF₂Br)CF₂]_P-, where R=-CH₂; mixture of -CH₂ and -CF₂, in which content of the R=CH₂ component is not less than 60 mol %; R_F=-CF₃; -OCF₃; -OCF₂CF₂CF₂OCF₃; -OCF₂CF₂(OCF₂)₂OCF₃; n=64.0 - 85.0 mol %.; p=0.3 - 3.0 mol %.; m= the rest up to 100 mol %; k=1-3.

EFFECT: obtaining vinylidene fluoride-based bromine-containing copolymers which do not contain gel, vulcanisates with high strength and elasticity.
