Summary: | The present invention relates to crosslinkable compositions comprising vinylidene fluoride (VDF)/trifluoroethylene (TrFE) polymers and a fluorine-containing crosslinking agent of formula (A) [agent (Cz)]: {N3[S(O)g1]s1}na-(RH)nh-Rf-(R′H)nh′-{[S(O)g2]s2N3}na′, formula (A) wherein each of g1 and g2, equal to or different from each other, is 1 or 2, each of s1 and s2, equal to or different from each other, is 0 or 1, each of na and na′ is independently zero or an integer of 1 to 3, provided that the sum na+na′ is at least 2, each of RH and R′H, equal to or different from each other, is a C1-C12 hydrocarbon group free of fluorine atoms, nh and nh′, equal or different from each other are independently 0 or 1, and Rf is selected from the group consisting of i) a C3-C20 fluorocarbon group, possibly comprising one or more ethereal oxygen atoms, ii) an oligomer comprising copolymerized units of vinylidene fluoride and trifluoroethylene, to a process for the manufacture of said compositions, to a method for curing the same, and to the use of said copolymers in electrical and electronic devices. |
