Poly (1-vinylimidazole) (PVI) resins were prepared with a metal ion as template by the radiation polymerization at room temperature. The metal (Ni2+, Co2+ and Zn2+) -1-vinylimidazole complex was copolymerized and crosslinked with 1-vinylpyrrolidone by γ-ray irradiation, followed by the removal of the template metal ion by treating the resins with an acid. These PVI resins adsorbed metal ions in the wide pH region more effectively than the PVI resins prepared without template, which is due to an increase in the number of adsorption sites (A8) and the larger stability constants (K) of the PVI resins prepared with template.
