发明名称 Production and recovery of poly(arylene sulfide ketone) and poly(arylene sulfide diketone) resins
摘要 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.
