ABSTRACT:
High molecular weight aromatic sulfide/sulfone polymers are produced by contacting a dihalo aromatic sulfone, an alkali metal sulfide other than lithium sulfide, a heterocyclic amine, and, optionally, an alkali metal carboxylate. Use of at least one heterocyclic amine with or without an alkali metal carboxylate during the contacting results in polymers of high molecular weight having utility as coatings, films, molded objects, fibers, and the like.
