Abstract
A polymer composition made by combining a polyketone polymer and a phenolic alkylene dicarboxylate of the general formula: ##STR1## each R.sup.1 independently is hydrogen or alkyl with 1-6 carbon atoms, each R.sup.2 independently is alkyl with 1-6 carbon atoms, each m is an integer of 0-4, and n is an integer of 2-12; and a process for preparing these compositions.
Claims21
