  • Cyanate ester resin blends with brominated styrene-containing polymers
    Patent number: 5091476
    Abstract: The fire retardant properties of polycyanates are improved by blending them with a brominated homopolymer or brominated interpolymer of styrene or alkyl- or halo-substituted styrene without an unacceptable sacrifice in the physical, thermal, electrical and moisture resistance properties.
    Type: Grant
    Filed: April 27, 1990
    Date of Patent: February 25, 1992
    Assignee: The Dow Chemical Company
    Inventor: Georgia A. Monnerat
  • Flame resistant polyaromatic cyanate resins with improved thermal stability
    Patent number: 4806625
    Abstract: Halogen-containing hydrocarbon phenol cyanate resins are prepared by reacting the product resulting from reacting a hydrocarbon phenol resin with a metahalogenated hydroxymethyl phenol with a cyanogen halide.
    Type: Grant
    Filed: January 12, 1988
    Date of Patent: February 21, 1989
    Assignee: The Dow Chemical Company
    Inventors: Gary W. Bogan, Georgia A. Monnerat
  • Laminates from epoxidized phenol-hydrocarbon adducts
    Patent number: 4710429
    Abstract: Laminates are prepared for reinforced expoxy resin compositions comprising (A) a reinforcing material such as fiberglass, (B) one or more epoxy resins such as a hydrocarbon-phenol eposy resin and (C) one or more epoxy resin curing agents such as a hydrocarbon-phenol resin or phenol-formaldehyde novolac resin. These laminates are particularly suitable for use in electrical applications such as the manufacture of printed circuit boards.
    Type: Grant

    Date of Patent: December 1, 1987
    Assignee: The Dow Chemical Company
    Inventors: Gary W. Bogan, Peter A. Lucas, Georgia A. Monnerat, Dale J. Aldrich
  • Durable epoxy resin
    Patent number: 4701481
    Abstract: Curable compositions are prepared from reinforced epoxy resin compositions comprising (A) a filler material such as silica flour, (B) one or more epoxy resins at least one of which is a hydrocarbon novolac epoxy resin such as a phenol-dicyclopentadiene epoxy novolac resin and (C) one or more epoxy resin curing agents such as phenol-formaldehyde novolac resin. These compositions are particularly suitable for use in electrical applications such as the encapsulation and subsequent protection of electrical and micro-electronic devices and circuitry and in adhesive formulations.

  • Catalyst for reacting phenolic hydroxyl groups with epoxy groups
    Patent number: 4341658
    Abstract: Catalysts for reacting vicinal epoxides with an aromatic hydroxyl-containing material result from the treatment of a solid substrate containing a plurality of ion-exchangeable cations with a polymer containing a multiplicity of quaternary onium cations in association with a reactive anion such that after treatment, there remains a sufficient quantity of the quaternary onium cations in association with the reactive anion to catalyze the reaction. These catalysts reduce the quantity of side reactions.
    Type: Grant

    Date of Patent: July 27, 1982
    Assignee: The Dow Chemical Co.
    Inventors: Georgia A. Monnerat, George E. Ham, Thomas J. Hairston, Melvin J. Hatch
