SPECTROSCOPIC STUDY OF THE COPPER-COMPLEX ES OF THE COPOLYMERS OF N-VINYLPYRROLIDONE OR N-(2-HYDROXYPROPYL)METHACRYLAMIDE WITH AMINO-ACID-RESIDUES

The formation of copper complexes of the copolymers of N-vinylpyrrolid one and allyl glycidyl ether modified with glycine or p-alanine and th e copolymers of N-(2-hydroxypropyl)methacrylamide with methacryloylgly cine and methacryloyl-beta-alanine were studied by UV visible spectrop hotometry and ESR spectroscopy. It was shown that, depending on the na ture of ligand and the pH of medium, either the carboxylate complexes or the chelate structures that involve one or two nitrogen atoms of am ino acid in cupric ion coordination are formed.
