Synergistic stabilizer compositions are employed to stabilize halogen-containingnvinyl polymers from, for example, degradation and discoloration. Thenstabilizer compositions comprise a dihydropyridine or polydihydropyridine, and atnleast one of an aminoalcohol of formula (3)n nwherein Y is a substituted or unsubstituted C 1 -C 36 alkyl, aryl, alkaryl, or aralkylngroup, R 1 and R 2 are each independently hydrogen or a substituted or unsubstitutednC 1 -C 36 alkyl, aryl, alkaryl, or aralkyl group, with the proviso that Y, R 1 , and R 2 arensubstituted so as to provide the aminoalcohol with two or more hydroxy groups; orna perchlorate salt. |
