摘要
从１，１′－联萘－２，２′－二胺出发，合成了旋光性二酐单体及相应的外消旋体：（Ｓ）－，（Ｒ）－和（±）－２，２′－（３，３′，４，４′－四酸二酐）二苯甲酰胺－１，１′－联萘．二酐与二胺单体通过溶液缩聚反应制得一系列旋光性聚酰胺酰亚胺．聚合物具有较好的热稳定性、旋光稳定性。
Novel optically active aromatic poly(amide imide)s(PAIs)
containing 1,1′ binaphthyl 2,2′ diyl units in the main chain were prepared by
polycondensation reactions of newly synthesized dianhydride, 2,2′ bis(3,4
dicarboxylzenzamido) 1,1′ binaphthyl dianhydride[( S ) BNDADA and (±) BNDADA], with
diamines. The properties of the resulted PAIs were fully characterized by a combination of
investigations on inherent viscosity, thermal properties(DSC and TGA), specific rotation, CD and
UV Vis absorbance. These PAIs showed good solubilities, thermal properties and optical
stabilities. Interesting UV Vis absorption behavior of films casted from these PAIs was
observed and analyzed.
