ABSTRACT OF THE DISCLOSURE A method for removing oligomers and non-polymeric impurities from poly(arylene sulfide) polymers is provided in which a poly(arylene sulfide) polymer associated with oligomers and non-polymeric impurities is contacted with a solvent at a sufficient temperature to substantially dissolve the oligomers and impurities but not the poly(arylene sulfide) polymer; then the polymer is separated from the solution containing the oligomers and impurities at an elevated temperature. A polymer product produced by this method is also disclosed.
