Abstract
A polyarylene sulfide is prepared in a reaction mixture containing a dihaloaromatic compound, a sulfur source, a polar organic compound and an alkali metal or alkaline earth metal dithionite. The presence of dithionite in the reaction mixture enables the production of polymer and products therefrom having a reduced Tmc and enhanced heat stability.
