Abstract
A method is provided for stabilizing a poly(arylene ether ketone), comprising the steps of: PA1 (a) digesting the poly(arylene ether ketone) in an aqueous medium to remove polymerization solvent, and PA1 (b) hydrothermally treating the poly(arylene ether ketone) by heating it to a temperature of at least 160.degree. C. while contacting it with water.
