    摘要: The present invention provides a lubricating composition comprising: (a) an oil of lubricating viscosity; and (b) a crosslinked polymer derived from monomers comprising: (i) 0.001 wt % to 7 wt % of a di- or higher functional crosslinking monomer; (ii) 30 wt % or higher of a hydrocarbyl-substituted (meth)acrylic monomer, wherein each hydrocarbyl contains greater than 8 carbon atoms; and (iii) 0 wt % to 40 wt % of a hydrocarbyl-substituted (meth)acrylic monomer, wherein each hydrocarbyl contains 8 or fewer carbon atoms. The invention further provides a method of preparing the crosslinked polymer and its use in a lubricating composition for lubricating an internal combustion engine.
