    摘要: A composition comprising a polymer mixture A of polymers formed by: (a) from 10 to 70% by moles of ethylene (E), (b) from 30 to 90%, by moles of a fluorinated monomer selected from tetrafluoroethylene (TFE), chlorotrifluoroethylene (CTFE), or mixtures thereof, (c) from 0.1 to 30% by moles, with respect to the total amount of monomers (a) and (b), of one or more acrylic monomers; characterized in that the polymer mixture A comprises polymer fractions having a different content of the acrylic comonomer such that the elastic modulus at 23null C. (ASTM D1708) of said polymer mixture A is lower than at least 10% of the elastic modulus of a polymer formed by monomers a), b) and c) wherein the polymer fractions have substantially an equal content of the acrylic comonomer.
