Abstract

A process for manufacturing an adsorbent for reducing the concentration of fibrinogen and/or fibrin in blood or blood plasma in which a carrier material, which is preferably a copolymer derived from (meth)acrylates and or (meth)acrylic acid amides, is activated by amination, and subsequently undergoes thermal treatment at a temperature of over 100° C. An adsorber for the purpose of reducing the concentration of fibrinogen and/or fibrin in blood or blood plasma may be produced from the adsorbent.
