A POROUS ABPBI [(PHOSPHORIC ACID DOPED POLY (2,5-BENZIMIDAZOLE)] MEMBRANE AND PROCESS OF PREPARING THE SAME

摘要

The present invention relates to a porous ABPBI (phosphoric acid doped poly (2, 5- benzimidazole)) membrane and process of preparing the same. A stable porous ABPBI (Phosphoric Acid Doped Poly (2, 5-benzimidazole)) membrane stable to acids, bases, solvents and autoclaving is disclosed. The membrane finds use for separation of solutes in solution in acids, bases and solvents.
