Abstract: Reaction of a carboxylic acid-containing polymer with certain aromatic amines results in dispersant viscosity modifiers with improved soot handling performance in heavy-duty diesel engines, compared with reaction with non-aromatic amines.

Abstract: An interpolymer composition comprising monomer-derived units of (i) at least one of an aliphatic olefin containing from 2 to 30 carbon atoms and a vinyl aromatic monomer, and (ii) at least one alpha, beta-unsaturated acylating agent; wherein a portion of said acylating agent monomers is esterified and wherein a portion of said acylating agent monomers is condensed with at leas t one aromatic amine, provides good viscosity modification and dispersancy performance.
