Abstract
The invention relates to a thermoplastic polymer-based battery separator, which contains a compound of formula R(OR.sup.1).sub.n (COOM.sup.x+.sub.1/x).sub.m. In said formula, R represents a non-aromatic hydrocarbon group comprising between 10 and 4,200 carbon atoms, which can be interrupted by oxygen atoms, R.sup.1 represents H, --(CH.sub.2).sub.kCOOM.sup.x+.sub.1/x or --(CH.sub.2).sub.k--SO.sub.3M.su-p.x+.sub.1/x, whereby k stands for 1 or 2, M represents an alkali or earth alkaline metal ion, H.sup.+ or NH.sub.4.sup.+, whereby not all variables of M are defined simultaneously as H.sup.+, n stands for 0 or 1, m stands for 0 or a whole number from 10 to 1,400 and x stands for 1 or 2. The ratio of oxygen atoms to carbon atoms in the compound according to the aforementioned formula ranges between 1:1.5 and 1:30 and n and m cannot simultaneously represent zero.
