Abstract
Binuclear copper(II) complexes prepared with the binucleating ligand 2,6-diformyl-4-methyl-phenol were attached as pendant groups to the polymers polyethyleneimine and polyvinylaminevinyl sulfonate sodium salt. The polymer-copper(II) complexes were characterized from optical and magnetic studies and their catecholase activities were measured in water. Polyvinylamine-vinylsulfonate-copper(II) is insoluble in water and showed little if any catecholase activity. The polyethyleneimine-copper complexes were reasonably soluble in water and demonstrated good catecholase activity. The catecholase activity of the polyethyleneimine-copper complexes increased in activity with an increase in the ratio of polymer-to-copper content (based on a constant copper concentration).
