  • Patent number: 4537952
    Abstract: This invention discloses a novel class of polymeric diphenylamine compounds. The compounds are produced by reacting diphenylamine with a dialkylalkenylbenzene or dihydroxyalkylbenzene having either meta or para orientation in the presence of an acid catalyst.
    Type: Grant
    Filed: May 21, 1984
    Date of Patent: August 27, 1985
    Assignee: The Goodyear Tire & Rubber Company
    Inventors: Richard E. Gloth, James J. Tazuma, Robert A. Smith
  • Patent number: 4463170
    Abstract: This invention discloses a novel class of polymeric diphenylamine compounds. The compounds are produced by reacting diphenylamine with a dihydroxyalkylbenzene having either meta or para orientation in the presence of an acid catalyst. The polymeric diphenylamine compounds are useful as antioxidants.
    Type: Grant
    Filed: January 26, 1983
    Date of Patent: July 31, 1984
    Assignee: The Goodyear Tire & Rubber Company
    Inventors: Richard E. Gloth, James J. Tazuma, Robert A. Smith
  • Patent number: 4417017
    Abstract: A class of novel polymeric diphenylamine compounds are used to provide antioxidant protection to oxidizable polymers. In particular, the polymeric reaction products of diphenylamine and 1,4-diisopropenylbenzene are used in acrylonitrilebutadiene and styrene-butadiene rubbers to protect these rubbers in high temperature, oxidative working environments.
    Type: Grant

    Date of Patent: November 22, 1983
    Assignee: The Goodyear Tire & Rubber Company
    Inventors: Richard E. Gloth, James J. Tazuma
  • Patent number: 4414348
    Abstract: There is disclosed a method for stabilization of polyester resins by incorporating in the resins novel polymeric diphenylamine compounds, produced by reacting diphenylamine with a dialkylalkenylbenzene or a dihydroxyalkylbenzene in the presence of an acid catalyst.
    Type: Grant
    Filed: January 26, 1983
    Date of Patent: November 8, 1983
    Assignee: The Goodyear Tire & Rubber Company
    Inventors: Richard E. Gloth, James J. Tazuma, Max H. Keck
  • Patent number: 4330462
    Abstract: There is disclosed a method for the stabilization of polyester resins by incorporating in the resins certain types of 4-mercaptophenol derivatives.
    Type: Grant
    Filed: May 12, 1980
    Date of Patent: May 18, 1982
    Assignee: The Goodyear Tire & Rubber Company
    Inventors: Max H. Keck, Richard E. Gloth, James J. Tazuma
  • Patent number: 4205160
    Abstract: The invention relates to polymers containing units of indane, 1-pentene and 2-pentene. These polymers can be formed by the polymerization of meta- or para-diisopropyl benzene diol or by the polymerization of meta- or para-diisopropenyl benzene in the presence of acid activated clay or other acidic catalysts.
    Type: Grant
