Abstract
A method is provided for recovering poly(arylene sulfide) polymers characterized by low ash and oligomer concentrations and having a larger particle size, which method comprises, during recovery, adding or maintaining a sufficient amount of a polar organic compound to the reaction mixture immediately after solidifying the poly(arylene sulfide) polymer.
