Abstract

Stabilized polyvinyl chloride molding compositions contain, per 100 parts by weight of polymer, 0.02 to 5 parts by weight compounds of Formula I, ##STR1## in which R represents an alkyl group with 1 to 19 carbon atoms, a cycloalkyl group with 5 or 6 carbon atoms, a phenyl group, an alkylphenyl group with 7 to 11 carbon atoms or an MOOC--CH.sub.2 group, n represents the numbers 0 and 1, and M represents sodium or potassium. Heat stabilizers which are metal soaps, aromatic metal carboxylates, metal phenolates and organotin compounds as well as crystalline sodium aluminosilicate are also incorporated.
