ABSTRACT
In the work was obtained cross-linked copolymers of salts of acrylic acid and 3-chloro-1,3-butadiene-2-phosphonic acids and N,N’-methylene-bis-acrylamide as crosslinking agent. The cross-linked copolymers described IR, NMR, 13C and 31P spectroscopy. The influence of external parameters (cycles of swelling-drying, freezing-heating, etc.) on the physicochemical characteristics of the materials was investigated. Sorption properties of the material in aqueous solutions with various mineral additives were investigated. The ability of the polymer material for retaining moisture was studied on the soil model.

Keywords: cross-linked copolymer, acrylic acid, 1,3-butadiene-2-phosphonic acid, agriculture, water retention.
