摘要：

Diamine amic acids were synthesized by reacting aromatic diamines with 3,3',4,4'-benzophenonetetracarboxylic dianhydride in dimethylacetamide and were characterized by melting points, elemental analyses, IR, H-1-NMR and HPLC. Poly(amide-amic acid)s were prepared by low temperature solution polycondensation of diamine amic acids with isophthaloyl chloride in dimethylacetamide. Poly(amide-imide)s with alternate (amide-amide) and (imide-imide) sequences were obtained by cycloimidization of poly(amide-amic acid)s with Et3N-Ac2O mixture in dimethylacetamide solution. They were characterized by solubilities, inherent viscosities, IR and H-1-NMR. Thermal properties of the polymers were measured by differential scanning calorimetry and thermogravimetric analyses.
