ELASTOMERIC COMPOSITION BASED ON COPOLYMER OF TETRAFLUOROETHYLENE AND PERFLUOROALKYL VINYL ESTERS Russian patent published in 2016 - IPC C08L27/18 C08K5/29 C08G73/24 C08K5/16 C08L27/12 C08F214/18 C08F214/26 C09K3/10

Abstract RU 2596746 C2

FIELD: chemistry.

SUBSTANCE: invention relates to elastomeric compositions based on copolymer of tetrafluoroethylene and perfluoroalkyl vinyl esters and can be used in oil refining and petrochemical industry. Composition based on ternary or quaternary copolymer tetrafluoroethylene, perfluoromethyl vinyl ester and perfluoroalkyl vinyl esters, containing nitrile group, containing vulcanising agent - salt of perfluorocyclohexane carboxylic acid of general formula , where R is -NH₂, -NH-NH₂ or n=2-8, m = 4-8 in following ratio of components, wt%: copolymer - 100, vulcanising agent - 2.0-4.0.

EFFECT: invention increases heat resistance of vulcanisates during ageing at high temperatures, absence of release of products, causing their corrosion.
