Abstract
The present disclosure relates to comb or brush polymers and, in some approaches, comb or brush polymers suitable for use as viscosity index improvers in lubricating oil compositions. The present disclosure further relates to oil compositions comprising such polymers. The disclosure also relates to brush polymer compositions derived from sulfur functionalized polydialkylsiloxane backbones and various (meth)acrylate monomers.
