Vulcanizable compositions of fluoroelastomers exhibiting improved processability and chemical stability.

摘要

Vulcanizable compositions of fluoroelastomers based in vinylidene fluoride and one or more monomers containing an ethylenic unsaturation and at least one fluorine atom, exhibiting improved processability and chemical stability and comprising, as a processing coadjuvant, a mono-or dihydroxypolyfluoroether having an average molecular weight ≧400 (monohydroxypolyfluoroethers) and ≧2500 (dihydroxypolyfluoroethers), respectively.
