  Polyalkyl(meth)acrylate based comb polymers with weight-average molecular weights of 700,000 g/mol or greater and number-average molecular weights of 130,000 g/mol or greater can be used to improve the high temperature-high shear performance of lubricant compositions, especially of engine oil (EO) compositions. These polymers can be obtained in a reaction mixture comprising monomers, a dilution oil, and an initiator. The resulting lubricant compositions can have improved kinematic viscosity and high temperature high shear performance.
