ABSTRACT:
The present invention relates to an adsorbent material for chromatography comprising a polymer immobilized onto a support, wherein the polymer backbone is attached to the support by one or more linkages which comprise one or more amide groups. It further relates to a method for preparing an adsorbent material for chromatography wherein a support is reacted with a polymer.
