The invention concerns a polymer product for immobilizing of metal ions, adsorption, and the like, with the structure
P - X - A - Q
wherein P is a hydrophilic polymer with a molecular weight of more than 3 000 Daltons. X is a heteroatom, O, S or N, A is an atom sequence with at least 3 carbon atoms, and Q is a group with at least two branches with terminal, metal chelate forming substituents, each having at least two hetero atoms, N, O or S, separated by two or at most three carbon atoms in a sequence or Q is a macrocyclic ring with at least 8 and not more than 30 atoms, at least 3 of which are nitrogen atoms, in sequence in the ring, and the preparation thereof which is done by activating a hydrophilic polymer with epoxi or vinylsulfone or inserting of aldehyde groups, coupling with tris-(2-aminoethyl)-amin and treating with reagents chosen from α-haloalkanoate, α-haloalkanoylhalogenide, o-amino- or hydroxysubstituted aromatic or heteroaromatic aldehyde, dialdehyde or diketone and ringclosing of at least two terminal N with a bridge.
