Abstract

See full text

There is provided a charge-mosaic membrane comprising a cationic block copolymer (P) having a vinyl alcohol polymer block (A) and a cationic-group containing polymer block (B) as components; and an anionic block copolymer (Q) having a vinyl alcohol polymer block (C) and an anionic-group containing polymer block (D) as components. Such a charge-mosaic membrane is useful as a charge-mosaic membrane for piezodialysis because it exhibits higher membrane strength and higher permselectivity and has a larger charge density and a larger salt permeation flux.
