Abstract: Novel optically active aromatic poly(amide imide)s(PAIs) containing 1,1′-binaphthyl 2,2′-diylunits 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.

Key words: Optically active polyimide, 1,1′-Binaphthyl, 2,2′-diyl unit, Axially dissymmetry
