Abstract: A stabilizer composition for halogenated polymers includes at least one compound from group A) and at least one compound from group B), group A) being composed of semicarbazides, carbazides, carbazones, and carbodiazones, and their salts, and group B) of guanidines and melamines, superacids and salts of superacids, epoxy and glycidyl compounds, 1,3-dicarbonyl compounds, polyols, sterically hindered amines, hydrotalcites, zeolites, and alkali metal aluminocarbonates, hydrocalumites, metal hydroxides, metal oxides, metal hydrogen carbonates, and metal carbonates, metal soaps, organotin compounds, organic phosphite esters, amino alcohols and hydroxyl-containing isocyanurates, ?,?-unsaturated ?-aminocarbonyl compounds, aminouracil compounds and aminothiouracil compounds, and compounds having at least one mercapto-functional, sp2-hybridized C atom. Polymers stabilized in accordance with the invention are notable in particular for improved initial color and also for improved color maintenance.
