Nickel stabilizers and dye enhancers for polyolefins

摘要

The addition of a nickel salt of an omega-[4-hydroxyphenyl]-alkanoic acid having at least two alkyl groups on the phenyl ring to a reaction product of a polyalkyl-substituted 4-hydroxy benzoic acid and a secondary or tertiary organic phosphite results in lubricated polyolefins having enhanced resistance to yellowing.
