ABSTRACT:
Nitrogen-containing copolymers are prepared by the reaction of lithiated hydrogenated conjugated diene-monovinylarene copolymers with nitrogen-containing organic compounds. The nitrogen-containing copolymers are oil additives which combine the aspects of viscosity index improvers with dispersant properties.
