ABSTRACT:
A process for preparing a grafted star polymer which comprises contacting a nitrogen-containing polymerizable organic polar compound with a star polymer (as hereinbefore defined) in the presence of a free radical polymerization initiator and characterized in that the reaction is carried out in a mineral oil solvent and, as coupling inhibitor, either a chain transfer agent, a pi-electron donor, or a comonomer, together with the modified, hydrogenated star polymers thus produced, and their use as luboil additives.
