ABSTRACT:
Polyarylene thioethers having increased melt crystallization temperature are produced by subjecting a polyarylene thioether recovered from a conventional polycondensation of dichlorobenzene with sodium sulfide to a treatment with an aqueous non-oxidative strong acid such asd HCl, H.sub.2 SO.sub.4 or H.sub.3 PO.sub.4 or with an aqueous salt of the non-oxidative strong acid with a weak base such as ammonia.
