Patent ID: 7037997

Claim:
In a method for producing a support matrix by copolymerising one or more monomers having one vinyl group (monomer I) with one or more vinyl monomers having two or more vinyl groups (monomer II), the improvement comprising adding a vinyl monomer (monomer III) having the formula: R′—B′—Ar(—CH═CH 2 ) n (3) in which Ar is an aromatic ring (arylene group); n is an integer >0; B′ is a bridge structure selected from a single bond and bivalent groups comprising a chain of atoms linking R′ to Ar and consisting of 1–10 atoms, selected from carbons and the heteroatoms: ether oxygen, thioether sulphur or amino nitrogen, with the proviso that the terminal atom in B′ which is attached to R′ is one of the heteroatoms; R′ is a (C 2-30 )-hydrocarbon group carrying two or more protected hydroxy groups; and copolymerizing the monomers.
