Abstract

In the present work we have synthesized two-component block- and graft copolymers MOPEO-b-PAAm, PAAm-b-PEO-b-PAAm and PVA-g-PAAm comprised methoxypoly(ethylene oxide), poly(ethylene oxide) or poly(vinyl alcohol) and chemically complementary polyacrylamide and also the grafted polymer-inorganic hybrid SiO2-g-PAAm based on monodispersed silica nanoparticles. These copolymers we used as special matrices in the process of borohydride reduction of Ag+ ions. It was established the influence of chemical nature, molecular architecture and concentration of the matrices and the content of silver nitrate on some reaction parameters, size and stability of Ag-nanoparticles in aqueous solutions.
