Complexation of poly(vinyl 2-aminoethyl ether) with Cu2+

Complexation of Cu 2+ with poly(vinyl 2-aminoethyl ether) and copolymer of N-vinylpyrrolidone and vinyl 2-aminoethyl ether in aqueous solutions was studied using the potentiometric titration, viscometry, IR and ESR spectroscopy methods. Formation of complexes having various composition, structure, and stability was established, the properties of the complexes being dependent on the nature of the reacting polyamines, their concentration and pH
