ABSTRACT:
Compositions comprising a poly(arylene sulfide) which crystallizes to a fine-grained crystalline morphology are provided. A method is also provided for treating compositions comprising a poly(arylene sulfide) by incorporation of a crystalline morphology altering additive, heating the resulting mixture above the melting point of the poly(arylene sulfide) and cooling the mixture at a rate of less than 50.degree. C. per minute. Exemplary additives include a poly(arylene sulfide-ketone) and a polyaryl ketone.
