ABSTRACT:
A method of purification of physiological liquids of organism has the step of passing a physiological liquid through a material which has a size, a shape, and a structure selected so as to remove toxic compounds from the physiological liquid and is composed of a partially chloromethylated porous highly crosslinked styrene or divinylbenzene copolymer which initially have surface exposed chloromethyl groups in which thereafter chlorine is replaced with an element which forms different surface exposed functional groups with a greater hydrophilicity and greater biocompatibility than that of the chloromethyl group.
