The present invention relates to a novel polymer with pendant groups. The invention further provides for a lubricating composition containing said polymer. The invention further provides a method and use of controlling viscosity index by supplying to an oil of lubricating viscosity the polymer with pendant groups.

Polymers and methods of controlling viscosity

The invention provides a lubricating composition containing an oil of lubricating viscosity and polymer with pendant groups. The invention further provides for a method of controlling viscosity index by supplying to an oil of lubricating viscosity the polymer with pendant groups.

Lubricating composition containing a polymer and antiwear agents

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 least one aromatic amine, provides good viscosity modification and dispersancy performance.
