    Abstract: Proposed is a processing additive for halogen-containing polymers, in particular for polyvinyl chloride, with a content of a synthetic, crystalline, finely particulate alkali metal alumo silicate containing 13 to 25 percent by weight of bound water, which--in its anhydrous form--is of the composition (0.7-1.1) Me.sub.2 O.Al.sub.2 O.sub.3 .times.(1.3-2.4) SiO.sub.2, Me standing for an alkali metal, wherein the alkali metal alumo silicate is present in combination with at least one isocyanuric acid derivative of the formula ##STR1## wherein each n stands for an integer from 0 to 5, preferably from 0 to 3, each X represents H or a straight or branched alkyl group having 1 to 6 carbon atoms, preferably 1 or 2 carbon atoms, and each R is --OH or --COOH, and wherein the n's, X's and/or R's preferably have the same meaning, as well as halogen-containing polymers stabilized with use of this combination.
