Description

ABSTRACT:
A process is provided for preparing more granular (i.e., higher bulk density) particulate poly(arylene sulfide ketone) or poly(arylene sulfide diketone) resins having associated therewith improved processability and thermal stability, without generating pressures significantly greater than those generated during polymerization reactions of particulate poly(arylene sulfide ketone) or poly(arylene sulfide diketone) resins.
