Interaction of poly(methacrylic acid) and bivalent counterions. I

Abstract
The calculation of formation curves of metal‐polyacid complexes from titration curves is discussed. The interaction of bivalent ions of Cu, Cd, Zn, Ni, Co, and Mg with poly(methacrylic acid) is investigated by this method. These metals seem to form complexes involving two carboxylate groups for each ion in a large domain of pH values. Formation constants for these complexes are given which decrease according to the order indicated above.
