1. A composition comprising a polymer grafted covalently onto a support, said polymer having a degree of polymerization np, ranging from 2 to 10,000, and containing np monomer units, said monomer units being:
either monomer units derived from 4-vinylpyridine, in which the carbons in positions 2 and 6 can be substituted by one of the substituents of the following group: hydrogen, alkene radical of 1 to 20 carbons, aryl radical of 1 to 20 carbons, carboxylic acid of 1 to 20 carbons, alcohol of 1 to 20 carbons, ether of 1 to 20 carbons, ester of 1 to 20 carbons, amine of 1 to 20 carbons other than heterocycles, amide of 1 to 20 carbons, thiols of 1 to 20 carbons, phosphine of 1 to 20 carbons,
or monomer units derived from a co-monomer,
provided that the two substituents cannot both be hydrogen,
and provided that said monomer units derived from the 4-vinylpyridine represent at least 20% of the degree of polymerization np,
said polymer being optionally complexed with a metal or a metal oxide,
said polymer being linear or crosslinked,
said polymer being irreversibly linked to a support.
