Abstract

The formation of cobalt particles in the presence of water-soluble polymers of various nature was studied. The use of polyethyleneimine made it possible to prepare a dispersion of cobalt particles with a narrow size distribution. The use of polystyrenesulfonic acid and poly-N-vinylpyrrolidone led to the formation of a dispersion of cobalt particles 1.8–35.0 nm in size. In the presence of polyacrylic acid, particles 3.5–19.5 nm in size are formed, which consist of cobalt oxide and metallic cobalt.
