The present invention relates to novel polymers. These polymers contain monomeric units derived from 4-vinylpyridine and monomer units derived from a comonomer. The polymers can be complexed with a metal, linear, or crosslinked. The present invention also relates to the processes for the preparation of these polymers, by radical polymerization, as well as their use for the capture of metals in aqueous media, in particular the capture of uranium in seawater or in nuclear waste from nuclear power plants, |
