Abstract

A polymeric film useful as an interelectrode separator or electrolyte member in electrolytic devices, such as rechargeable batteries, comprises a copolymer of vinylidene fluoride and hexafluoropropylene, a medium to high-boiling plasticizer, and a finely divided inorganic filler which has been subjected to actinic radiation or thermal energy to cause crosslinking thereof in the presence of a crosslinking agent selected from the group consisting of an acrylate ester, di- or triallyl ester and a di- or triglycidyl ether.
