Use of vinylidenfluoride (VDF) copolymers for preparing electrolyte polymers, wherein the VDF copolymers have the following polymeric structure (I): (CH2-CF2)m-(CXY-C(ORf)Z)n-(CF2-CF(CF3))p) wherein: Rf is a perfluoroalkyl group having from 1 to 3 carbon atoms; X, Y, and Z equal to or different from each other are selected from F, Cl or H; m,n and p are integers, n or p can be 0 but not simultaneously; said VDF copolymers being obtainable by emulsion polymerization at 75-120 DEG C, preferably 95 DEG -120 DEG C, in the presence of organic initiators. |
