ABSTRACT:
An oil soluble nitrogen containing grafted degraded ethylene copolymers useful as multifunctional viscosity index improvers or modifiers, such as VI improver-dispersant additives. The nitrogen containing grafted degraded ethylene copolymers are grafted with an ethylenically unsaturated carboxylic acid grafting material and the grafted degraded ethylene copolymers are then reacted with at least one polyamine containing one primary amine group and at least one or more secondary amine groups.
