Difunctional monomers containing functional moieties suitable for forming azole rings and for forming aromatic ketone or sulfone moieties can be reacted in strong, non-oxidizing, dehydrating acids to form copolymers containing benzazole moieties and aromatic ketone or sulfone moieties. Those copolymers can be extruded to form fibers and films which are thermoplastic.
