Abstract : Para-ordered aromatic heterocyclic polymers characterized by having p-benzbisoxazole, p-benzbisthiozole or p-benzbisimidazole units and containing diphenoxybenzene structures. The diphenoxybenzene structures function as 'swivels' in the polymer chains, imparting flexibility thereto and making it possible to cast strong films from solutions of the polymers. (Author)
