ABSTRACT:
Purification of physiological liquids of organism is performed by passing a physiological liquid with toxicants removed from a patient through a material which has a size a shape, and a structure selected so as to remove toxic compounds in the molecular range of 300 to 30000 Dalton from the physiological liquid and which is composed of a porous hydrophobic divinylbenzene 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.
