摘要：We report our work for preparing cross-linked polyimide via a series of imide functional benzoxazine resins as precursors. The structures of synthesized monomers have been confirmed by H-1 NMR and FT-IR. Among this class of benzoxazine monomers, the ortho-imide functional benzoxazine resins show useful features both in the synthesis of benzoxazine monomers and the properties of the corresponding thermosets. For the cross-linked polyimides based on ortho-imide functional benzoxazine, an additional route is adopted to form a more thermally stable cross-linked polybenzoxazole with the release of carbon dioxide. The ortho-imide functional benzoxazine resins show the possibility to form high performance and even super high performance thermosets with low cost and easy processability. The thermal properties are evaluated by DSC and TGA. (c) 2015 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym. Chem. 2015, 53, 1330-1338
