The monomer 2,6,12-triaminotriptycene was synthesized and the structure was confirmed by IR and (1)H NMR spectra. Hyperbranched polyimides modified with different terminal groups were obtained from precursors, anhydride- and amino-terminated hyperbranched poly(amic acid)s from polymerization of A(2) + B(3) system. From gel permeation chromatogram (GPC) characterization, representative products had high molecular weight. All polymers had good solubility in CHCl(3), DMF and tetrahydrofuran (THF), and performed no detective T(g)s in the range of 50-300 degrees C and high T(d)s above 455 degrees C when 5% weight loss.
