Abstract

The process of hydrolysis of amide groups of polyacrylamide in the presence of a dispersion of nanosized copper particles obtained by the reduction of copper cations with sodium tetraborate was studied. Quantum chemical calculations showed an increase in the effective positive charge on the carbon atom in the amide group upon formation of a complex with copper. Calculation of the energy of interaction of polyacrylamide and polyacrylic acid macromolecule units with copper particles showed the possibility of replacing amide groups of the polymer that underwent hydrolysis from the surface of copper particles with amide groups that did not participate in the reaction. The degree of hydrolysis of polyacrylamide in the presence of copper particles was 89%, and in the absence of particles 22%.
