Disclosed are novel polymers that are grafted onto a substrate. These polymers contain monomer units derived from 4-vinylpyridine and monomer units derived from a co-monomer. The polymers may be complexed with a metal, and linear or crosslinked. Also disclosed are methods for preparing these polymers by radical polymerisation, as well as to their use for metal capture in aqueous media, particularly uranium capture in seawater or in final nuclear waste from nuclear power plants.
