Abstract: The present invention pertains to a process for the manufacture of a dense film. The process includes processing, in a molten phase, a solid composition [composition (C)] comprising;
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—(CH2CHRAO)n—RB  (I) 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)]; 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 this process and to the use of the dense film as dense separator in electrochemical devices.
