Abstract
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)]: {N[S(O)]}—(R)—R—(R')—{[S(O)]N}, 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 Rand R′, equal to or different from each other, is a C-Chydrocarbon group free of fluorine atoms, nh and nh′, equal or different from each other are independently 0 or 1, and Ris selected from the group consisting of i) a C-Cfluorocarbon 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.
