ABSTRACT:
Polymers containing both oxadiazole and imide recurring units are made from soluble polymeric precursors that contain hydrazide and/or amic acid recurring units. Dehydration of the hydrazide produces the oxadiazole unit and dehydration of the amic acid produces the imide unit. The oxadiazole unit may also be advantageously formed in various monomeric hydrazine compounds. The monomeric hydrazine compounds are made reactive by converting the dinitroso form of the compound into a reactive diamino form. The polymers may be used as molding and laminating resins, wire coatings, films, filaments and adhesives.
