Novel optically active aromatic poly(amide-imide)s (PAIs) were prepared from newly synthesized 2,2Π-bis(3,4-dicarboxybenzamido)-1,1Π-binaphthyl dianhydride ((Ο©)-, (S)-, and (R)-BNDADA). PAIs based on dianhydride monomers with different ee % were investigated with respect to their structures and chir
