PP-II-140In the presence of 10 % copper PGU complex supported on alumina optimumcyclohexane:H 2 O 2 :catalyst ratio is formed which provides maximum accumulation of theproducts.Thus, immobilized copper complexes supported on inorganic oxide are active catalystsfor cyclohexane oxidation under mild conditions. Interaction of Cu ions with carboxyl groupsof PGU and formation of polymer-metal complexes was confirmed by IR and EPRspectroscopy methods.420
