| 中文摘要 | cis-1,2,3,4-cyclohexanetetracarboxylic dianhydride (cis-1,2,3,4-chda) was synthesized. it was found that under such conditions as heating or boiling in acetic anhydride, cis-1,2,3,4-chda could be converted to its trans-isomer. the process of thermal isomerization was monitored by h-1 nmr spectra and the mechanism of conversion was proposed. their absolute structures of cis- and trans-1,2,3,4-chdas were elucidated by single crystal x-ray diffraction. the polycondensations of cis- and trans-1,2,3,4-chdas with aromatic diamines such as 4,4'-oxydianiline (oda), 4,4'-methylenedianiline (mda), 4,4'-diamino-3,3'-dimethyldiphenylmethane (dmmda), 4,4'-bis(4-aminophenoxy)benzene (tpeq), 2,2-bis[4-(4-aminophenoxy)phenyl] propane (bapp) were studied. it is easy to obtain higher molecular weight polyimides from trans-1,2,3,4-chda using conventional one-step or two-step methods. however, higher molecular weight polyimides derived from cis-1,2,3,4-chda could not be prepared by the usual methods (solid content ca. 10%) owing to the trend of forming cyclic oligomers. |
