Abstract
The present disclosure relates to star polymers and, in some approaches, star 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 star polymer compositions derived from a sulfur functionalized chain transfer agent core and select (meth)acrylate monomers.
