Abstract
Disclosed is a method for producing material for purification of physiological liquids of organism. A material has a size, shape and structure selected so as to remove toxic compounds in the molecular range of 300 to 3000 Dalton, and the material is produced from a porous hydrophobic divinylbenzne copolymer, which initially has surface exposed vinyl groups, in which thereafter the vinyl groups are chemically modified so as to form different surface exposed functional groups with a greater hydrophilicity and greater biocompatibility than those of the vinyl groups.
