Abstract: Abstract Two novel unsymmetric diamine isomers, 6-amino-2-(4-(4-aminophenoxy)phenyl)-1H-benzimidazole (3p) and 6-amino-2-(3-(4-aminophenoxy)phenyl)-1H-benzimidazole (3 m), were synthesized and employed to react with several aromatic dianhydrides to yield two new series of poly (benzimidazole imide)s (PBIPIs), PI-4 (a-e) and PI-5… read more here.
