Title: Processing aid for poly(arylene sulfide) resins

Abstract: A method for improving processability of compositions of normally solid polymers of arylene sulfide by the addition of an amount of solid ethylene polymer effective to improve the processability of the composition. A composition of matter of normally solid poly(arylene sulfide) and an amount of solid ethylene polymer effective to improve processability of the composition. In a preferred embodiment the amount of solid ethylene polymer in the total composition is in the range of about 0.1 to about 5 weight percent.
