Polysaccharide matrix having a grafted polymer, method for producing the same and use thereof

Abstract

A porous, non-particulate, convectively permeable polysaccharide matrix has a surface on which there is fixed a grafted-on polymer derived from at least one ethylenic monomer compound having functional groups, wherein the polysaccharide matrix is prepared by grafting a porous, non-particulate, convectively permeable polysaccharide starting matrix with the at least one ethylenic monomer compound in the presence of an organic acid having at least one carboxylic acid group and/or at least one acidic XH group, where X=—O, —S, or —N, and of a transition metal or lanthanide compound. The polysaccharide matrix has a high protein binding capacity. A process for preparing the polysaccharide matrix and a method for using the polysaccharide matrix for material separation also are provided.
