Abstract
A process for producing a poly(arylene sulfide) polymer comprising (a) polymerizing reactants in a reaction vessel to produce a poly(arylene sulfide) reaction mixture, (b) processing at least a portion of the poly(arylene sulfide) reaction mixture to obtain a poly(arylene sulfide) reaction mixture downstream product, and (c) contacting a by-product treatment additive with at least a portion of the poly(arylene sulfide) reaction mixture and/or downstream product thereof, and (d) processing at least a portion of the poly(arylene sulfide) reaction mixture downstream product to yield salt solids particulates, wherein the by-product treatment additive reduces agglomeration of the salt solids particulates.
