| Summary: | The paper presents results on copolymerization of α-halogens acrylic acid and
N-vinylpyrrolidone in the presence of aminating agents at low temperatures in an organic environment. The IR spectra of the obtained copolymers confirm the amination reaction. The dependences of the reduced viscosity of synthesized polymers aqueous solutions were studied and a «polyelectrolyte swelling» was observed. The synthesized aminated polymers form internal complex compounds with divalent metal halides at room temperature. This paper describes the first attempts to obtain new nanocomposite materials based on synthesized copolymers and modified montmorillonite. Analysis of the literature data shows that the features of obtaining nanocomposites based on Na+-montmorillonite and water-soluble copolymers have not been studied before. |
