Anionic copolymers of acrylamide and polyacrylic acid as hydroaccumulating polymeric materials

A method for hydrogels production by the formation of cross-linked binary polymer complexes is proposed. Necessary conditions for synthesis were determined, providing a high degree of swelling of hydroaccumulating polymeric materials based on anionic copolymers of acrylamide and polyacrylic acid. Chemical interaction of components of polymer complex has been proved by the methods of infrared spectroscopy and potentiometric titration. The possibility of moisture absorption control of hydrogels depending on synthesis conditions and application purpose was shown.
