Abstract

Stabilized chlorine-containing polymer compositions comprising a chlorine-containing polymer and a stabilizer mixture comprising: PA1 a) at least one cyclic or non-cyclic, sterically hindered amine, PA1 b) at least one organic zinc compound and/or inorganic zinc compound from the series consisting of carbonates, chlorides, sulfates, oxides, hydroxides, basic oxides and mixed oxides, and PA1 c) at least one compound from the series consisting of the crystalline alkali metal/alkaline earth metal aluminosilicates, and, if desired, PA1 d) at least one 1,3-diketone and/or PA1 e) at least one organic or inorganic calcium compound. Polymer compositions of this type are preferably employed for slush mould and crash pad applications.
