A new imide-containing phthalonitrile resin has been synthesized and studied by thermal analysis. The initially formed di(amic acid) phthalonitrile intermediate, which was synthesized from reaction of 4-(3-aminophenoxy)phthalonitrile with 3,3',4,4'-benzophenonetetracarboxylic dianhydride, is readily converted into the imide linkages before commencing with the polymerization reaction. The monomer was polymerized in the presence of a minute quantity of 1,3-bis(3-aminophenoxy)benzene by an addition polymerization reaction. Thermal properties were determined by differential scanning calorimetry and thermogravimetric analysis.
