摘要 Two aromatic polyimides were prepared by two- step way. Firstly, the poly(amic acid)s were synthesized from 1, 3 - bis(4 - aminophenoxy)benzene and two different aromatic dianhydrides. Secondly, polyimides were prepared via thermal imidization of poly(amic acid) precursors. The polyimides prepared were insoluble in common organic solvents such as tetrahydrofuran, chloroform and N, N- dimethyiformamide. The inherent viscosities of poly(amic acid)s were 1.82 dL/g and 2.67 dL/g. The high inherent viscosities were due to the strong intra- or intermolecular hydrogen interaction. The polyimides were characterized by mechanical and thermal analysis. It was found that the samples are of excellent thermal stability, higher glass-transition temperature and excellent dynamic mechanical and thermal properties.
