Hydroperoxidized ethylene copolymers and terpolymers as dispersants and V. I. improvers

摘要

Lubricating oil compositions containing multifunctional additives, e.g. sludge dispersants and V.I. improvers, and the use of the composition to lubricate the crankcase of an internal combustion engine are disclosed. The additives are prepared by hydroperoxidizing ethylene copolymers and terpolymers.
