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_gs in the range of 50-3℃ and high Tds(5%)above 455℃.
