Abstract
This invention provides a novel permselective polymeric membrane excellent in permselectivity which allows permeation of water in an aqueous solution at a high rate but is highly preventive of permeation of solutes, and a process for the preparation of such permselective membrane, said polymeric membrane consisting essentially of a linear polymer containing N-aryl-substituted-benzimidazole units as the main-chain-constituting units.
