ABSTRACT:
This invention provides a method for producing high temperature aromatic sulfide polymers which are well suited for use as base compounds in conductive applications. In the method of the present invention, sulfur and a bridged diaromatic reactant compound are reacted in an inert polyhaloaromatic solvent and in the presence of a strong Friedel-Crafts metallic halide catalyst. One novel polymer produced by the method of the present invention is poly(phenoxathiinyl sulfide).
