Reactions of guanidine polymethacrylate with zinc(II) tetra-4-sulfophthalocyanine sodium salt in aqueous media

The interaction of the zinc(II) tetra-4-sulfophthalocyanine sodium salt with guanidine polymethacrylate has been studied by electronic absorption (EAS) and IR spectroscopy and viscosimetry. It was found that the reaction between the macroheterocyclic compound and the polymer proceeds due to the binding of the sulfo groups of metallophthalocyanine and the guanidine cation of the polymer, which leads to an extension of the polymer knot and stabilization of its conformation.
