Abstract

Stabilizers for chlorine-containing olefin polymers containing Ca complexes of 1,3-diketones, hydrocarbon waxes and esters and/or partial esters of saturated, straight-chain C.sub.12 -C.sub.34 monocarboxylic acids, in conjunction with zinc salts of saturated, straight-chain C.sub.8 -C.sub.22 monocarboxylic acids and esters of phosphorous acid, provide the polymers with excellent properties in regard to processibility and temperature stability.
