NMR spectroscopy of Cu(II) complexes with acrylamide and sodium acrylate copolymer and ω-amino acids

Macromolecular complexes of acrylamide and sodium acrylate copolymer with microelements, including Cu(II), may form at preparation crop protection stimulation compositions, where the serves as an adhesive, water-retaining film-forming agent. Preparations for production also contain amino acids that protect plants under stressful conditions (cold, dry, etc.). Carboxylic groups copolymer, carboxylic be involved in mixed Cu(II) ions formation. Number methylene separating group affects its ability to a stable chelate cycle and, therefore, ligand composition acid. This work is aimed determining macromolecular ion ω-amino (β-alanine, γ-aminobutyric acid, ε-aminocaproic acid). 13C 1H NMR spectroscopy was used clarify composition. A complex are ligands has been found aqueous solutions acid acid) molar ratio – equal 1 : 6. both β-alanine coordination discovered solution containing ions, β-alanine, well COO− 6 30. participate formation well. have shown either or ε-aminokaproic copolymer.
