HIGHLY CROSS-LINKED PEARL-LIKE HYDROPHOBIC SUPPORT MATERIAL CAPABLE OF BEING ACTIVATED, METHOD FOR MODIFYING SAID SUPPORT MATERIAL AND METHOD FOR ADSORBING BIOLOGICALLY ACTIVE SUBSTANCE FROM WATERY LIOUID OR CHROMATOGRAPH- ING FOR REMOVAL OF LARGE AMOUNT OF SAID SUBSTANCE

摘要

PURPOSE: To provide a pearl-like carrier material which has simultaneously a high-hydrophilicity, an easy activatability, a high toughness under the condition of water-saturation and a high hydrolysis-resistance in aqueous-alkaline medium. CONSTITUTION: The carrier material is based on a copolymer comprising radical- polymerizable, hydrophilic etheric unsaturated monomers and radical polymerizable ethylenically unsaturated groups are crosslinked with polyfunctional monomer units.
