Abstract

The present invention relates to a polymer composition comprising a surfactant interacting additive, and wherein the polymer composition further comprises at least one silanol condensation catalyst, wherein each catalyst is selected from: i) a compound of formula I ArSO3H (I) or a precursor thereof, wherein Ar is an 1 to 4 alkyl groups substituted aryl, wherein the aryl is phenyl or naphthyl, and wherein each alkyl group, independently, is a linear or branched alkyl with 10 to 30 carbons, wherein the total number of carbons in the alkyl groups is in the range of 20 to 80 carbons; ii) a derivative of i) selected from the group consisting of an anhydride, an ester, an acetylate, an epoxy blocked ester and an amine salt thereof which is hydrolysable to the corresponding compound of formula I; and iii) a metal salt of i) wherein the metal ion is selected from the group consisting of copper, aluminum, tin and zinc; an article, for example, a coating, a wire or a cable, comprising the polymer composition, a process for producing an article and use of the polymer composition.
