Abstract
The present disclosure relates to polymers suitable for viscosity index improvers in lubricating oil compositions and further relates to oil compositions comprising such polymers. The disclosure also relates to polymer compositions derived from alkyl (meth)acrylate monomers and selected molar ratios of the (meth)acrylate monomers in the polymer suitable to use as viscosity modifiers.
