METHOD OF PRODUCING SILVER NANOCOMPOSITIONS BASED ON SYNTHETIC WATER-SOLUBLE POLYMERS Russian patent published in 2013 - IPC C01G5/00 B82B3/00 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing compositions of silver nanoparticles based on water-soluble synthetic copolymers. The method involves reducing silver ions in the presence of a water-soluble polymer. The polymers used, which combine properties of a silver ion reducing agent and a stabiliser of the formed nanoparticles, are copolymers of 2-deoxy-2-methacrylamido-D-glucose with 2-dimethylamino-ethylmethacrylate or 2-diethylamino-ethylmethacrylate of general formula: , where R: if R₁ n, m=5-95 mol. %, and for R₂ n=63-95 mol. %, m=5-37 mol. %, characteristic viscosity [η]=0.06-0.30 dl/g. The method is realised by reacting said polymers with AgNO₃ in an aqueous solution at room temperature and natural light with polymer concentration of 0.010-0.100 g/ml, AgNO₃ concentration of 0.001-0.01 g/ml.

EFFECT: obtaining silver nanoparticles at room temperature with natural light and without use of an inert atmosphere.
