Abstract:
A material for purification of physiological liquids of organism, comprising a polymeric 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 chloromethyl groups, said surface exposed functional groups of greater hydrophilicity and enhanced biocompatibility being covalently bonded lipid-like structures selected from a group consisting of phosphatidyl choline, phosphatidyl serine, and phosphatidyl 2-ethanol amine.
