Title:
COMPOSITION, LUBRICATING OIL COMPOSITION AND GREASE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2023/190808
Kind Code:
A1
Abstract:
Provided is a composition which contains metal-based nanoparticles (X), a polymer (Y) and a dispersion medium. The polymer (Y) is a vinyl polymer having a straight chain alkyl group having 10-28 carbon atoms and a nitrogen-containing heterocyclic group. The metal-based nanoparticles (X) and the polymer (Y) are dispersed in the dispersion medium. The composition can be used as an additive composition for a lubricating oil composition, an additive composition for a grease composition, a lubricating oil composition or a grease composition. The polymer (Y) is at least one type selected from the group consisting of: a polymer (Y1) containing two or more types selected from the group consisting of constituent units derived from a monomer (ya), constituent units derived from a monomer (yb) and constituent units derived from a monomer (yc); and a polymer (Y2) which contains constituent units derived from the monomer (yb) and does not contain constituent units derived from the monomer (ya) or constituent units derived from the monomer (yc). Monomer (ya): an olefin having 12-30 carbon atoms. ·Monomer (yb): a vinyl monomer having a nitrogen-containing heterocyclic group in which at least one hydrogen atom is substituted with a straight chain alkyl group having 12-30 carbon atoms. Monomer (yc): a vinyl monomer having a nitrogen-containing heterocyclic group in which no hydrogen atoms are substituted with a straight chain alkyl group having 12-30 carbon atoms
