| 中文摘要 | a novel dianhydride, 3,3'-dioxo-[1,1']-spirodiphthalan-5,5',6,6'-tetracarboxlic dianhydride, was synthesized and used as a monomer to prepare polyimides with several diamines via a conventional two-stage procedure. the intermediate poly(amic-acid)s had inherent viscosities of 0.84-1.71 dl/g and could be thermally converted into lightly yellow, transparent, flexible and tough films. films cast from chemically imidized polyimides were transparent and colorless. the glass transition temperatures (tg) were > 400 degrees c, and the 5% weight-loss temperatures were > 420 degrees c in n-2 and in air. the solubilities of these polyimides in various solvents were evaluated. the mechanical properties of some polyimides were also tested.
