Abstract: The present invention pertains to a process for the manufacture of a dense film, said process comprising, preferably consisting of the following steps: a) providing a solid composition [composition (C)] comprising, preferably consisting of: at least one vinylidene fluoride (VDF) fluoropolymer comprising one or more carboxylic acid functional end groups [polymer (F)], at least one poly(alkylene oxide) (PAO) of formula (I): HO—(CH2CH RAO)n—RB, wherein RA is a hydrogen atom or a C1-C5 alkyl group, RB is a hydrogen atom or a —CH3 alkyl group and n is an integer comprised between 2000 and 40000, preferably between 4000 and 35000, more preferably between 11500 and 30000, and optionally, at least one inorganic filler [filler (I)]; and b) processing said composition (C) in molten phase thereby providing a dense film having a thickness of from 5 μm to 30 μm. The present invention also pertains to the dense film provided by said process and to use of said dense film as dense separator in electrochemical devices.
