A comb copolymer viscosity modifier may be made by polymerization comprising at least, or consisting essentially of, the following monomers: (a) (optionally from 7.0 wt % to 18 wt %, by repeat units, of) a hydrogenated polybutadiene-based (alk)acrylate ester macromonomer; (b) (optionally from 33 wt % to 64 wt % or from 38 wt % to 58 wt %, by repeat units, of) a C3-C8 alkyl (alk)acrylate ester monomer; (c) (optionally up to 35.0 wt %, by repeat units, of) a C12-C24 alkyl (alk)acrylate ester monomer; and (d) (optionally from 3.0 wt % to 27 wt %, by repeat units, of) a C6-C20 aryl, aralkyl, or alkaryl (alk)acrylate ester monomer, such that a sum of repeat units due to (c) plus (d) constitute at least 21.0 wt % of repeat units of the comb copolymer viscosity modifier. Lubricant compositions comprising the comb copolymer viscosity modifier, as well as uses thereof and methods for modifying viscosity and dispersancy, are also contemplated.
