Zusammenfassung:Vinylidenfluoride (VDF) thermoplastic copolymers, comprising: (a) from 0.1 to 10% by moles, preferably from 0.5 to 5%, of one or more fluorodioxoles of formula: wherein Y is equal to ORf wherein Rf is a perfluoroalkyl having from 1 to 5 carbon atoms, or Y = Z as defined hereinunder; Y is preferably equal to ORf; X1 and X2, equal to or different from each other, are -F or -CF3; Z is selected from -F, -H, -Cl; (b) VDF, being the remaining part to 100% by moles.
