ABSTRACT:
A process for obtaining an aromatic sulfide polymer which has a markedly high molecular weight and can be readily formed into films, fibers, and other structures. The process comprises heating, to a temperature of 100.degree. to 270.degree. C. in an organic solvent under the coexistence of a very small amount of water, a dihaloaromatic compound and a substantially anhydrous amorphous vitreous compound composed of (i) S.sup.2- anions and other inorganic salt-forming anions and (ii) ions of an alkali metal and/or an alkaline earth metal.
