Abstract:
A composition of the reaction product of (a) an isobutylene-diene copolymer having thereon groups containing carboxylic acid functionality or reactive equivalent thereof, derived from an α,β-unsaturated carboxylic compound; and (b) an amine component comprising at least one aromatic amine containing at least one N—H group capable of condensing with said carboxylic acid functionality, is a useful dispersant viscosity modifier.
