ABSTRACT:
An ion exchanger comprising a crosslinked copolymer and an ion exchange group, wherein an alcoholic hydroxyl group is bonded directly to the skeleton of a matrix of totally porous organic synthetic crosslinked copolymer. The ion exchanger has a predetermined hydroxyl group content, predetermined ion exchange group content, predetermined water regain value and predetermined specific surface area. The ion exchanger having a high mechanical strength and high chemical stability and not causing non-specific adsorption of bio-substances is useful as a high-speed liquid chromatography packing material and separating membrane, especially for bio-substances, such as protein, enzyme, peptide, amino acid, nucleotide or the like.
