FIELD: chemistry.
SUBSTANCE: invention relates to polymer-inorganic compositions in the form of nanoparticles and their production methods. A polymer-inorganic composition in the form of nanoparticles for use as an additive for a lubricating material composition is proposed, obtained by grinding of a mixture containing one or more intercalation compounds (A) including metal chalcogenide, and one or more polymer compounds (B) obtained by polymerization of a monomer composition containing dimethylaminopropylmethacrylamide, a mixture of laurilmethacrylate and butylmethacrylate, and a product of reaction of composite ester of (meth)acrylic acid and hydroxylated hydrogenated polybutadiene with average molecular weight from 500 to 10,000 g/mol, wherein the mass ratio of (A) to (B) is from 20:1 to 1:5. A method for the production of the specified composition, its use as an additive to a lubricating material composition, and a composition for use as an additive, containing the specified composition, are also proposed.
EFFECT: proposed composition allows for obtainment of additives for lubricating material with improved anti-scuff and antifriction characteristics, stable during long time in lubricating oil.
