Abstract
Vulcanizable compositions of fluoroelastomers based on vinylidene fluoride with one or more monomers containing an ethylene unsaturation and at least one fluorine atom, having improved processability and improved chemical stability, and comprising, as a processing coadjuvant, a mono- or dihydroxypolyfluoroether having a means molecular weight higher than or equal to 400 for the monohydroxypolyfluoroethers and higher than or equal to 2500 for the dihydroxypolyfluoroethers.
