Separating material (I) comprises a crosslinked synthetic polymer, a crosslinked agarose, a crosslinked dextran or a composite material from inorganic carrier with an organic coating as a carrier material, where: copolymers are covalently bonded on the surface of carrier material; the base carrier contains aliphatic hydroxyl group; the copolymers contain at least two different monomer units; the monomer units are connected linearly; and the copolymers comprise at least one monomer units with charge in the form of e.g. sulfonic acid, or at least one uncharged amide monomer unit (1a). Separating material (I) comprises a crosslinked synthetic polymer, a crosslinked agarose, a crosslinked dextran or a composite material from inorganic carrier with an organic coating as a carrier material, where: a mixed polymer is covalently bonded on the surface of carrier material; the base carrier contains aliphatic hydroxyl group; the copolymers contain at least two different monomer units; the monomer units are connected linearly; the copolymers comprise: at least one monomer units with charge in the form of a sulfonic acid or a carboxylic acid or in the form of an amine- or ammonium having group and containing alkyl- and/or alkylene group and optionally amide group, or at least one uncharged amide monomer unit of formula (R 1>-CH=C(R 2>)-C(=O)-N(R 3>)-Y 1>) (1a); the charge of the copolymer is free of aryl groups; only monomer units of the same charge are combined, if more than one monomer is included with charge; and the ratio of the monomer with charge to the monomer without charge is 1:99-90:10. R 1>H; R 2>H or CH 3; and R 3>, Y 1>H, straight-chain alkyl having up to 4C, methoxypropyl, ethoxyethyl or methoxyethyl. An independent claim is included for a process for preparing graft copolymer from porous particles containing hydroxyl group on surfaces, or other mould bodies, comprising chemical reaction of a graft polymer comprising two or more repeated monomer units, where at least one unit contains charge and at least one of unit contains uncharged group, one- or two alkyl- and/or alkoxyethyl- or alkoxypropyl substituents carries amide group, which is bonded to the hydroxyl group containing surface to form a material by ionic interaction of charged substances, preferably biopolymers capable to bind. |
