Abstract The water‐soluble polymer 4 containing pendant 8‐hydroxyquinoline (oxine) moieties was prepared and its reactivity with metal ions was studied by means of ultraviolet (UV) spectrophotometry. Polymer 4 was found to form complexes with metal ions in a mole ratio of 2 : 1 (oxine : metal), which is also obtained for the metal complexes of model compound 3 except for the Mg 2+ complex. Polymer 4 hardly reacts with Mg 2+ , while model compound 3 forms a 1 : 1 mol/mol complex. The stability of the complexes of polymer 4 with metal ions was found to decrease in the following order: Cu 2+ > Ni 2+ > Zn 2+ > Cd 2+ > Hg 2+ > Mg 2+ .
