Process for Production of Poly(Arylene Sulfide)

摘要

A process comprising (a) reacting a sulfur source and a dihaloaromatic compound in the presence of a polar organic compound to form a reaction mixture, (b) quenching the reaction mixture by adding a quench liquid thereto to form a quenched mixture, wherein the quench liquid comprises a particle size modifying additive, and (c) cooling the quenched mixture to yield poly(arylene sulfide) polymer particles. A process for producing a poly(phenylene sulfide) polymer comprising (a) reacting a sulfur source and a dihaloaromatic compound in the presence of N-methyl-2-pyrrolidone to form a reaction mixture, (b) quenching the reaction mixture by adding a quench liquid thereto to form a quenched mixture, wherein the quench liquid comprises a particle size modifying additive selected from the group consisting of sodium acetate, sodium benzoate, lithium acetate, lithium benzoate, lithium formate, sodium formate, and combinations thereof, and (c) cooling the quenched mixture to yield poly(phenylene sulfide) polymer particles.

1. A process comprising:
(a) reacting a sulfur source and a dihaloaromatic compound in the presence of a polar organic compound to form a reaction mixture; (b) quenching the reaction mixture by adding a quench liquid thereto to form a quenched mixture, wherein the quench liquid comprises from about 1 wt. % to about 80 wt. % of a particle size modifying additive, based on a total weight of the quench liquid; and (c) cooling the quenched mixture to yield poly(arylene sulfide) polymer particles.
