  • Polymeric step ladder polysuccinimide compositions suitable for lubricating oil dispersants and fuel additives
    Patent number: 5062980
    Abstract: Polymeric step ladder polysuccinimide compositions prepared by coupling the polyamine segments of polyalkenyl succinimides with dicarboxylic acids are useful as improved lubricating oil dispersants which are more compatible with engine seals made of synthetic rubbers such as Viton.RTM. than existing additives.
    Type: Grant
    Filed: October 30, 1989
    Date of Patent: November 5, 1991
    Assignee: Texaco Inc.
    Inventors: Cyril A. Migdal, Robert H. Jenkins, Jr.
  • Multifunctional lubricant additive with Viton seal capability
    Patent number: 4973412
    Abstract: A lubricating oil composition having improved antioxidancy, dispersancy and Viton seal compatibility. The antioxidant-dispersant being prepared by coupling partially acylated succinimides with an organic diacid, followed by further treatment with an unsaturated fatty acid, and then reaction of the nitroso group of an antioxidant aromatic amine with the unsaturated fatty acid to provide the lubricant product.
    Type: Grant

  • Reactive, non-yellowing triazine compounds useful as UV screening agents for polymers
    Patent number: 4962142
    Abstract: Triazine compounds are disclosed which are useful for imparting UV screening properties to polymers of the formula: ##STR1## wherein R is an electron withdrawing group; R.sub.1 is H, ##STR2## where R.sub.3 is an alkyl group having from one to about six carbon atoms; and R.sub.2 is selected from H and CH.sub.3, also disclosed are polymer compositions having improved UV screening properties containing said triazine compounds.
    Type: Grant
    Filed: November 14, 1988
    Date of Patent: October 9, 1990
    Assignee: Milliken Research Corporation
    Inventors: Cyril A. Migdal, John B. Hines, Edward W. Kluger
  • Antioxidant dispersant polymer dendrimer
    Patent number: 4938885
    Abstract: An antioxidant, dispersant lubricating composition comprises the product produced by first reacting an alkyl acrylate with an amine to produce an intermediate product, a first generation polyamine ester dendrimer which is then treated with an amine to produce a first generation polyamidoamine dendrimer which is then reacted with an acrylate to produce a second generation polyamidoamine ester dendrimer which with an amine is converted to a second generation polyamidoamine dendrimer which is then reacted with a polyisobutenyl succinic acid anhydride to produce the reactant product a polyisobutenyl succinimide-polyamidoamine dendrimer polymer.
