NEW OPTICALLY ACTIVE ORGANO-SOLUBLE POLY(AMIDE-IMIDE)S FROM [N,N'-(4,4'-DIPHTALOYL)-BIS-L-AMINO DIACID]S AND 1,2-BIS[4,4'-AMINOPHENOXY] ETHANE: SYNTHESIS AND CHARACTERIZATION

NEW OPTICALLY ACTIVE ORGANO-SOLUBLE POLY(AMIDE-IMIDE)S FROM [N,N'-(4,4'-DIPHTALOYL)-BIS-L-AMINO DIACID]S AND 1,2-BIS[4,4'-AMINOPHENOXY] ETHANE: SYNTHESIS AND CHARACTERIZATION

Six new dicarboxylic acids 3a-f were synthesized by the reaction of 3,3',4,4'-biphenyltetracarboxylic dianhydride (BPDA) 1 with L-amino acids 2a-f in a solution of glacial acetic acid/pyridine (Py) at refluxing temperature. Then six new optically active poly(amide-imide)s (PAI)s with good...
