Ann E. Aulabaugh 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).

  • Polymers derived from allylphenol or substituted allylphenol and maleic anhydride
    Patent number: 4388451
    Abstract: A copolymer formed by reacting maleic anhydride or a maleimide or a mixture of these with an allylphenol, a methallylphenol, or substituted allyl or methallylphenol. The anhydride polymers are characterized as having a 1:1 molar ratio of maleic anhydride to phenol or substituted phenol. The maleic anhydride copolymers are water soluble materials, useful as epoxy resin modifiers and curatives, as ion exchange resins or membranes, laminates, and detergent additives and builders. The maleimide containing copolymers are also useful as epoxy resin modifiers and useful in the production of laminates, composites and coatings.
    Type: Grant

  • Copolymers derived from 1,3 dioxepins and maleic anhydride or maleimides and methods
    Patent number: 4384093
    Abstract: Copolymers and terpolymers formed by reacting either 4,7-dihydro-1,3-dioxepins or 6,7-dihydro-1,3-dioxepins with maleic anhydride and/or a maleimide. The copolymers are characterized as linear, low molecular weight, water soluble alternating copolymers. These copolymers are useful as a water soluble polymer, as epoxy resin modifies and curing agents. The copolymers formed from 4,7-dihydro-1,3-dioxepins and maleic anhydride can be rearranged to form a poly (.gamma.
