In a stabilized polyvinyl chloride molding mixture containing a stabilizer combination based upon alkali metal, alkaline earth metal, and/or zinc soaps, powdered, crystalline, hydrous aluminosilicate, and flow promoters, the improvement which comprises, per 100 parts by weight of polyvinyl chloride, (a) from about 0.2 to 5 parts by weight of a synthetic, crystalline, powdered alkali metal aluminosilicate containing from about 13 to 25 percent by weight of water of crystallization, which has the composition 0.7-1.1Me2O.Al2O3.1.3-2.4SiO2 wherein Me represents an alkali metal, with respect to the anhydrous form; and (b) from about 0.1 to 5 parts by weight of at least one compound selected from the group consisting of b1-CO-CHR2-CO-R3 wherein R1 and R3, which may be identical or different, each represent a linear or branched alkyl or alkenyl having from 1 to 36 carbon atoms, an aralkyl having from 7 to 36 carbon atoms, or an aryl or cycloaliphatic having less than 14 carbon atoms, the cycloaliphatic group optionally being olefinically unsaturated and R1 and R3 being unsubstituted or substituted, and R2 represents hydrogen or an alkyl or alkenyl of from 1 to 36 carbon atoms, and R1 and R2 may form a divalent alkylene with from 2 to 5 carbon atoms.
