  • Bis-m-benzotrifluoride compounds
    Patent number: 5498691
    Abstract: Disclosed are bis-meta-benzotrifluoride compounds having the general formula ##STR1## where each A is independently selected from the group consisting of NO.sub.2, NH.sub.2, and NH.sub.3.sup.+ Z.sup.-, Z.sup.- is an anion and B is selected from the group consisting of O, CO, S, SO, and SO.sub.2. The diamine compounds are useful as monomers in making polyimides, polyamide-imides, and polyamides.
    Type: Grant
    Filed: October 9, 1990
    Date of Patent: March 12, 1996
    Assignee: Occidental Chemical Corporation

  • Glycidyl diamines containing aromatic trifluoromethyl group and epoxy resins prepared therefrom
    Patent number: 5283270
    Abstract: Disclosed are glycidyl diamines having the formulas ##STR1## where n is 1 or 2, m is 0, 1, or 2, X is Y or ##STR2## and Y is --, O, S, SO, SO.sub.2, CO, C(CH.sub.3).sub.2, or C(CF.sub.3).sub.2. An epoxy resin can be made by mixing the glycidyl diamine with an epoxy curing agent. The epoxy resins can be used as adhesives or to make composites.

    Date of Patent: June 16, 1992
    Assignee: Occidental Chemical Corporation
    Inventors: Robert A. Buchanan, Robert L. Ostrozynski, Henry C. Lin
  • Silicone-modified polyester resin and silicone-sheathed polyester fibers made therefrom
    Patent number: 4766181
    Abstract: Polyester resin is modified with siloxane block polymers in such a manner so as to form silicone-modified polyester copolymer domains of controlled size and distribution dispersed in the polyester matrix. These domains undergo microphase segregation and migration during the melt spinning and cold-drawing to the surface of the polyester fiber being formed so as to provide a silicone-sheathed polyester fiber.
    Type: Grant
    Filed: September 18, 1986
    Date of Patent: August 23, 1988
    Assignee: Union Carbide Corporation
    Inventors: Robert L. Ostrozynski, George H. Greene, James H. Merrifield
