中文摘要	novel optically active aromatic poly(amide-imide)s (pais) were prepared from newly synthesized 2,2'-bis(3,4-dicarboxybenzamido)-1,1'-binaphyl dianhydride ((+/-)-, (s)-, and (r)-bndada). pais based on dianhydride monomers with different ee % were investigated with respect to their structures and chiroptical properties. these polymers were highly soluble in polar aprotic solvents such as n,n-dimethylacetamide, n-methyl-2-pyrrolidone, pyridine, etc., and showed high glas s transition temperatures of 287-290 degrees c and 5% weight loss temperatures of 450-465 degrees c in nitrogen. optically active pais exhibited high specific rotations, excellent optical stabilities, and a dependence of optical activities on temperature. investigations on chiroptical properties indicated that chiral conformation was possessed by optically active pais.
