ABSTRACT:
The invention pertains to hydrophilic macroporous threedimensional copolymers of hydroxyalkyl methacrylates or hydroxyalkyl acrylates (C.sub.1 -C.sub.4 hydroxyalkyl) with crosslinking monomers which contain covalently attached saccharides via an O-glycosidic bond. The invention further pertains to the method of manufacturing of these copolymers by the direct reaction of the basic three dimensional copolymer containing hydroxyl groups with saccharides or their derivatives in an inert organic solvent under catalysis of HCl, BF.sub.3, or their mixtures at 20.degree.-100.degree. C. Saccharides and their derivatives are selected from the group comprising monosaccharides, oligosaccharides, deoxy sugars, amino saccharides, acylated saccharides, ether or halogen derivatives of monosaccharides and oligosaccharides, and the like. The invention also pertains to the application of these macroporous three dimensional copolymers with saccharides as sorbents and materials for the affinity chromatography for isolation of physiologically effective materials which contain free bonding sites for saccharides and are able to form specific complexes with saccharides.
