PURPOSE: A manufacturing method of porous polybenzimidazol is provided to secure the excellent permeability and selectivity for all kinds of gas by including well-connected picopores. CONSTITUTION: A manufacturing method of porous polybenzimidazol comprises the following steps: preparing polyaminoimide by reacting aromatic amine with more than two amino groups, and acid dianhydride; obtaining polypyrrolone form the polyaminoimide; alkali-processing the polypyrrolone; and heat-processing the alkali processed polypyrrolone. |
