SYNTHESIS OF POLY (BIBENZIMIDAZOLE-P-PHENYL- BENZOBISOXAZOLE)

A diacid monomer of benzobisoxazole 2, 6-di(p-phenylene-carboxylic) acid (BBODPA) was synthesized in a simple procedure, and characterized by means of FTIR, ¹H NMR and 13C NMR. The resulting BBODPA was polymerized with 3, 3'-diaminobenzidine tetrahydrochloride (DAB) to prepare poly (bibenzimida...
