METHOD TO DECREASE CORROSIVENESS OF REACTANTS IN POLY(ARLENE SULFIDE) POLYMER PRODUCTION

摘要

A process is provided for producing a poly(arlene sulfide) polymer in which polymerization reactants comprising an aqueous alkali metal hydroxide and a polar organic compound are pre-reacted at a fist temperature to form a mixture, then the mixture is reacted with a sulfur source at a second temperature under conditions sufficient to remove at least a portion of the water that is contained in the mixture, thereafter the thus dehydrated mixture is contacted with at least on dihaloaromatic compound under polymerization conditions.
