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.

Une purification de liquides physiologiques de l'organisme est effectuée par passage d'un liquide physiologique contenant des agents toxiques extraits d'un patient à travers un matériau présentant une taille, une forme et une structure sélectionnées pour permettre d'extraire les composés toxiques dans la plage moléculaire de 300 à 30 000 daltons du liquide physiologique, lequel matériau se compose d'un copolymère de divinylbenzène poreux hydrophobe contenant initialement des groupes vinyle exposés en surface, dans lequel les groupes vinyle sont ensuite modifiés chimiquement pour former différents groupes fonctionnels exposés en surface ayant une hydrophilie et une biocompatibilité supérieures à celles des groupes vinyle.
