ABSTRACT:
It is herein disclosed a process for stabilizing freshly prepared polyketone polymer comprising the step of contacting said polymer with a stabilizing agent selected from the group consisting of acidic water and an inorganic phosphate compound in water. The inventive process results in stabilized polyketone polymers having and exhibiting improved thermal oxidative and melt stability properties.
