ELASTOMERIC COMPOSITION BASED ON COPOLYMER OF TETRAFLUOROETHYLENE AND PERFLUOROALKYL VINYL ESTERS Russian patent published in 2012 - IPC C08L27/18 C08K5/29 B82B1/00 

Abstract RU 2470964 C2

FIELD: chemistry.

SUBSTANCE: composition contains a ternary or quaternary copolymer of tetrafluoroethylene and perfluoroalkyl vinyl esters, containing a cyano group, 1-4 pts.wt perfluorodiimidoyl amidine as a vulcanising agent and 0.5-2 pts.wt amorphous nano-sized polytetrafluoroethylene with number-average mean particle diameter of 300-1300 nm per 100 pts.wt copolymer.

EFFECT: vulcanisates obtained from the composition have a light colour and, along with improved physical and mechanical properties, have high resistance to nitric acid and high heat-resistance after ageing.
