Abstract:
1. A method for the production of a cross-linked support matrix in form of a porous monolith or particles that packed to a chromatographic bed will permit liquid flow velocities above 5 cm/h, preferably above 50 cm/h, to pass through the bed for at least 1 hour, comprising the steps of: (a) providing a starting support matrix that has pendent unsaturated groups, and (b) subjecting said starting support matrix to electron beam or gamma-ray irradiation to effect crosslinking, wherein the staring support matrix has been obtained by polymerizing a mixture of monomers carrying one or more unsaturated groups, at least one of said monomers carrying two or more unsaturated groups (monomer I).
