Abstract of the Disclosure The heat stability of arylene sulfide polymers, such as poly(p-phenylene sulfide) is improved by the addition of cure retarders comprising metal sorbates and, optionally, an alkaline earth metal nitrite. The improved heat stability is useful when the polymer is used in the production of fibers and films where it is desirable that the melt flow and molecular weight remain substantially unchanged during processing.
