<p>A process comprising heating for a sufficient period of time and at a temperature in the range of the glass transition temperature of the polymer to 5 degrees C below the melting point of the polymer, a solid, comminuted, copoly(arylene sulfide) prepared by reacting at a polymer producing temperature a mixture of a diiodoaromatic compound and elemental sulfur which contains less than 0.05 weight percent carbon, the copoly(arylene sulfide) corresponding to the structure: [(-A-S-)1-x(-A-S-S-)x]n, wherein A is a divalent substituted or unsubstituted aromatic radical, x is in the range of 0.2 to 0.005 and n is at least 100.</p> |
