A PROCESS FOR PREVENTING THIOPHENOL FORMATION AND/OR ACCUMULATION DURING PRODUCTION OF POLY(ARYLENE SULFIDE)

摘要

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 reactive aryl halide with at least a portion of the poly(arylene sulfide) reaction mixture and/or downstream product thereof, wherein before and/or after the contacting, the poly(arylene sulfide) reaction mixture and/or downstream product thereof comprise less than about 0.025 wt.% thiophenol, based on the total weight of the poly(arylene sulfide) reaction mixture and/or downstream product thereof.
