  • Dispersant viscosity modifiers based on diene-containing polymers
    Patent number: 7750089
    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 ?,?-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.
    Type: Grant
    Filed: March 8, 2005
    Date of Patent: July 6, 2010
    Assignee: The Lubrizol Corporation
    Inventors: Christopher Kolp, Matthew D. Gieselman, Renee A. Eveland, Philip Pike, John K. Pudelski, Michael J. Covitch, Christopher Friend
  • Substrates With Modified Carbon Surfaces
    Publication number: 20080067123
    Abstract: A process for functionalizing a carbon surface and the product thereof is disclosed. The first reactant used contains one or more electron withdrawing groups that thereafter can be reacted with other compounds. The reaction product has enhanced dispersability, interaction with other media, or other utilitarian uses, e.g. a reactive surface. The reaction product is then incorporated into an elastomeric or thermoplastic composition; it can be dispersed in a liquid media such as an ink, coating, or lubricant; or it can be used as a solid in applications such as a filtering media.
