Abstract
The paper presents the results of the reduction of nickel particles to copolymers based on unsaturated polyester resins with unsaturated carboxylic acids, as acrylic acid. It was found that at a ratio of the nickel concentration to sodium borohydride, nanosized nickel particles can be obtained. Dispersion of the metal-containing particles formed during the reduction is considered. The UV absorption spectra were used to analyze the absorption of the spectra of the initial nickel solution and after reduction with sodium borohydride. The study of the surface of synthesized nanocomposites showed pores in which the reduction reactions of nickel ions can take place.
