摘要： 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.

摘要： Deep curable polymers having heterocyclic ring systems such as isoindoloquinazolinedione ring systems prepared from novel cyanoimide polymers, most desirably 2'-cyanoimide polymers. Preferably the cyanoimide polymers are prepared from a diamine having at least one nitrile group in the two position to an amine group and a dianhydride having at least two cyclic anhydride groups. Copolymers may be prepared having other linkages, notably imide linkages, in addition to isoindoloquinazolinedione ring systems and/or other similar heterocyclic ring systems. The copolymers can be prepared by use of diamines containing one or more cyanoimide groupings and/or imide groups in their structure.
