Abstract:
A method for forming a polyarylene sulfide is described. The method can include a multi-step cooling and precipitation process in which the cooling rate of the solution that carries the polymer is decreased during a portion of the overall cooling. This slower cooling period can encompass at least a portion of the period during which the polymer precipitates from the solution. The precipitation process can form polyarylene sulfide particles with good particle integrity and a narrow particle size distribution, which can reduce fines and improve downstream processing and final product characteristics.

Claim (Index 46):
The particles of  claim 45 , wherein the first cooling rate is about 1\u00b0 C. per minute or greater and the first temperature is from about 235\u00b0 C. to about 245\u00b0 C., the second cooling rate is about 1\u00b0 C. per minute or less and the second temperature is from about 220\u00b0 C. to about 230\u00b0 C., and the third cooling rate is about 1\u00b0 C. per minute or greater.
