Abstract:
1. An adsorbent material, based on crosslinked, porous imidazole-divinylbenzene copolymers, for application in blood-, blood plasma-, and albumin purification processes, said adsorbent material being formed by radical suspension polymerization of a monomer mixture of divinylbenzene crosslinker and an imidazole derivative, wherein the polymerization is conducted in the presence of air and/or oxygen, a salt, a stabilizer, and an inert substance; the adsorbent material contains 5 weight % to 30 weight % of the imidazole derivative; the adsorbent material has a specific surface from 200 m the adsorbent material is essentially of spherical shape having a particle size range from 1 μm to 300 μm and an average pore diameter in the range of 100 Å to 500 Å.
