Abstract:
1. A method for the extracorporeal treatment of blood, blood plasma or blood serum, the method comprising: a) providing a solid substrate having a substrate surface, wherein primary or secondary amines are coupled to the substrate surface; and b) forming a graft polymer on the substrate by a process consisting essentially of: i) covalently coupling the primary or secondary amines with a thermally labile radical initiator and, subsequently, ii) contacting the substrate surface with a solution of one or more polymerizable monomers, wherein thermally initiated graft copolymerization of the monomers forms a structure comprising adjacent functional polymer chains on the substrate surface, to form a separating material; c) i) extracorporeally separating the blood into the blood cells and the blood plasma or blood serum and contacting the blood plasma or blood serum with the separating material, or ii) passing the blood plasma or blood serum through the separating material, or iii) passing whole blood onto or by the separating material.
