DISPERSANT VISCOSITY MODIFIERS BASED ON MALEIC ANHYDRIDE-STYRENE COPOLYMERS
摘要
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.
