ABSTRACT:
High molecular weight aromatic sulfide/sulfone polymers are produced by reacting a dihalo aromatic sulfone, an alkali metal sulfide other than lithium sulfide, an organic amide, and an alkali metal carboxylate. Use of the alkali metal carboxylate results in polymers of high molecular weight and satisfactory melt flow properties having utility as coatings, films, molded objects, fibers, and the like.
