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—(CH.sub.2CHR.sub.AO).sub.n—R.sub.B  (I) wherein R.sub.A is a hydrogen atom or a C.sub.1-C.sub.5 alkyl group, R.sub.B is a hydrogen atom or a —CH.sub.3 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.

A polyetherimide composition includes specific amounts of a polyetherimide, a block polyestercarbonate, a block poly-carbonate-polysiloxane, and a core-shell impact modifier in which the core includes a polysiloxane and the shell includes a poly(alkyl (meth)acrylate). Relative to a corresponding composition lacking the core-shell impact modifier, the polyetherimide composition exhibits increased impact strength while substantially retaining flame retardancy. Also described are associated articles, including articles formed by additive manufacturing, and a method of additive manufacturing.
