ABSTRACT:
A method for making compatibilizer for a concentrated viscosity index improving polymer blend includes polymerizing a mixture of (meth)acrylate monomers in the presence of a polyolefin polymer. A concentrated blend of viscosity index improving polymers includes a non-nitrogenous dispersant poly(meth)acrylate copolymer, a polyolefin copolymer, the compatibilizer and a hydrocarbon diluent.
