| 中文摘要 | a series of optically active poly(ester imide)s (pesi's) has been synthesized by the polycondensation reactions of new axially asymmetric dianhydrides, that is, (r)-2,2'-bis(3,4-dicarboxybenzoyloxy)-1,1'-binaphthyl dianhydride and (s)-2,2'-bis(3,4-dicarboxybenzoyloxy)-1,1'-binaphthyl dianhydride, and various diamines with aromatic, semiaromatic, and aliphatic structures. the polymers have inherent viscosities of 0.45-0.70 dl/g, very good solubility in common organic solvents, glass-transition temperatures of 124-290 degreesc, and good thermal stability. wide-angle x-ray crystallography of these polymers shows no crystal diffraction. in comparison with model compounds, an enhanced optical rotatory power has been observed for the repeat unit of optically active pesi's based on aromatic diamines, and it has been attributed to a collaborative asymmetric perturbation of chiral 1,1'-binaphthyls along the rigid backbones. |
