The complexes comprises heavy metal ions and a polymer containing 50-99.5 wt.% polymerised units of at least one basic vinylheterocyclic compound (I) with a pKa value of at least 3.8, and 0-49.5 wt.% units of other copolymerisable monomers (II), made in the absence of a polymerisation initiator and in the presence of 0.5-10 wt.% on monomers of a crosslinker (III).
