Abstract
A process comprising contacting a reaction product composition comprising a poly(arylene sulfide) composition and a polar organic compound, wherein the polar organic compound comprises greater than or equal to about 1 wt. % thiophenol, with a C4-C30 α,β-unsaturated ketone, a C4-C30 α,β-unsaturated ester, a C4-C30 α,β-unsaturated amide, or any combination thereof, wherein after the contacting, the polar organic compound comprises less than about 1 wt. % thiophenol. A process comprising contacting a composition comprising a polar organic compound and greater than or equal to about 1 wt. % thiophenol with a C4-C30 α,β-unsaturated ketone, a C4-C30 α,β-unsaturated ester, a C4-C30 α,β-unsaturated amide, or any combination thereof, to form a composition comprising the polar organic compound and less than about 1 wt. % thiophenol.
