Abstract : Oligomeric monomers are produced by reaction of a bisphenol compound with either a dihalobenzophenone or a (2, 2) bis (4-halophenyl) hexafluoropropane and any other activated halogen containing aromatic compounds in the presence of a base and an appropriate solvent. The resulting oligomeric product, a dialkaline bisphenate terminated salt is then reacted with 4- nitrophthalonitrile to form an oligomer-based phthalo- nitrile. These oligomers, in the presence or absence of an curing agent, may then be heated to form high temperature thermosetting polymers. These polymers can potentially be used as advanced materials for composites, as adhesives, and for microelectronic applications. (jg)
