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 the poly(arylene sulfide) reaction mixture to obtain a poly(arylene sulfide) polymer and a by-product slurry, (c) removing (e.g., evaporating) at least a portion of the by-product slurry to yield salt solids particulates, wherein at least a portion of the evaporating is carried out while simultaneously sizing the salt solids particulates to a desired size.
