Abstract
The invention relates to support material usable as such in chromatography or as a starting material which, upon linkage to it of compounds containing ionic groups, ligands or biomacromolecules, can be used as ion exchanger, as a medium in affinity chromatography or in enzymatic reactions and consists of porous, inorganic silanized particles onto which there is covalently bonded an organic, stationary phase built up of (co)polymerized vinyl monomers containing amide groups, said inorganic particles having been silanized with an organo silane.
