Claim 3:
4. The composition (C) of claim 1, wherein said fluoroelastomer (A) comprises recurring units derived from at least one (per)fluorinated monomer, wherein said (per)fluorinated monomer is selected from the group consisting of:
C2-C8 fluoro- and/or perfluoroolefins;
C2-C8 hydrogenated monofluoroolefins;
1,2-difluoroethylene, vinylidene fluoride (VDF) and trifluoroethylene (TrFE);
(per)fluoroalkylethylenes complying with formula CH2═CH—Rf0, in which Rf0 is a C1-C6 (per)fluoroalkyl or a C1-C6 (per)fluorooxyalkyl having one or more ether groups;
chloro- and/or bromo- and/or iodo-C2-C6 fluoroolefins;
fluoroalkylvinylethers complying with formula CF2═CFORf1 in which Rf1 is a C1-C6 fluoro- or perfluoroalkyl;
hydrofluoroalkylvinylethers complying with formula CH2═CFORf1 in which Rf1 is a C1-C6 fluoro- or perfluoroalkyl;
fluoro-oxyalkylvinylethers complying with formula CF2═CFOX0, in which X0 is a C1-C12 oxyalkyl, or a C1-C12 (per)fluorooxyalkyl having one or more ether groups;
functional fluoro-alkylvinylethers complying with formula CF2═CFOY0, in which Y0 is a C1-C12 alkyl or (per)fluoroalkyl, a C1-C12 oxyalkyl or a C1-C12 (per)fluorooxyalkyl, said Y0 group comprising a carboxylic or sulfonic acid group, in its acid, acid halide or salt form;
(per)fluorodioxoles, of formula:, , wherein, each of Rf3, Rf4, Rf5, Rf6, equal to or different from each other, is independently a fluorine atom, a C1-C6 fluoro- or per(halo)fluoroalkyl, optionally comprising one or more oxygen atom.
