Polymethacrylates as high vi viscosity modifiers |
abstract |
A lubricating composition contains an oil of lubricating viscosity and 0.5 to 10 percent by weight of a poly(meth)acrylate viscosity modifier polymer comprising (i) 15 weight percent to 35 weight percent monomer units of methyl (meth)acrylate, (ii) 0 to 10 weight percent monomer units of one or more C 2 -C 6 alkyl (meth)acrylates, (iii) 50 to 85 weight percent monomer units of one or more C 8 -C 30 alkyl (meth)acrylates, and (iv) 0 to 10 weight percent monomer units of one or more nitrogen-containing monomers. Such a lubricating composition exhibits a high viscosity index and may impart improved fuel economy to an internal combustion engine. |
