摘要：

Based on monomer 2,6,12-triaminotriptycene, hyperbranched polyimides with high molecular weight modified with different terminal functional groups were obtained by polymerization of A(2) + B(3) system. The prepared hyperbranched polyimides had good solubility in CHCl(3), DMF and THF, and performed no detective T(g)s in the range of 50-330 degrees C and high T(d)s (5%) above 455 degrees C.
