ABSTRACT:
It is herein disclosed a process for stabilizing freshly prepared polyketone polymer comprising contacting the polymer with a sufficient quantity of a stabilizing agent such as a polyaromatic or hydroaromatic compound. The inventive process results in stabilized polyketone polymers having and exhibiting improved thermal oxidative stability properties. It is also disclosed a stabilized polymer composition comprising a major amount of a polyketone polymer and a minor amount of a polyaromatic or hydroaromatic compound.
