Harold E. Doorenbos has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Monoadduct monomers and polyadduct polymers from divinyl ketones
    Patent number: 4672136
    Abstract: Included are monoadduct monomers made from divinyl ketones wherein only one vinyl bond therein has added to it a nucleophilic precursor. Nucleophilic precursors include phenols, thiols, secondary amines, amino acids, hydrocarbyl phosphites and phosphite esters, organic bis(phosphonites, the bisulfite anion and others.Polyadduct polymers made from the monoadduct monomers. The polyadduct polymers may be homo- or copolymers and may contain a pendant nucleophile residue.
    Type: Grant
    Filed: December 24, 1985
    Date of Patent: June 9, 1987
    Assignee: The Dow Chemical Company
    Inventors: Harold E. Doorenbos, Giffin D. Jones
  • Eneynols from acetylenes and propargylic alcohols
    Patent number: 4620045
    Abstract: Eneynols are prepared from terminal acetylenes and propargylic alcohols using a Cu.sup.+, Ag.sup.+ and/or Au.sup.+ halide catalyst.

    Inventors: Giffin D. Jones, Harold E. Doorenbos
  • Perfluorinated para-diketone polymers
    Patent number: 3996200
    Abstract: Two new organic compounds are disclosed, perfluorocyclohexane-1,4-dione and perfluorocyclohexene-1,4-dione, which are obtained concurrently or alternatively by reacting fluoranil with substantially pure anhydrous cobalt trifluoride. These compounds are clear, colorless liquids which are useful as monomers in the synthesis of thermally stable elastomeric polymers. Also disclosed is the dihydrate of said perfluorocyclohexane-1,4-dione, namely, octafluoro-1,1,4,4-cyclohexanetetraol.
