Rebecca E. McCluney 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).

  • Acrylate copolymer pressure-sensitive adhesive coated sheet material
    Patent number: 5057366
    Abstract: The invention provides normally tacky and pressure-sensitive adhesive compositions comprising a polymer having an inherent viscosity greater than 0.2 and having in its backbone at least a major portion by weight of polymerized monomeric acrylic or methacrylic acid ester of a non-tertiary alcohol and, having attached to the backbone, polymeric moieties having a weight average molecular weight of above about 2,000 and a T.sub.g of above about 20.degree. C. The number and composition of the attached moieties in the polymer is such as to provide the adhesive composition with a shear holding value of at least 50 minutes. Sheet materials coated with the adhesive composition are also provided. Preferred adhesive composition comprises a copolymer monomeric acrylic or methacrylic acid ester of non-tertiary alcohol and macromolecular monomer. The copolymer may also include up to 12% by weight of a copolymerizable polar monomer such as acrylic acid.
    Type: Grant
    Filed: September 16, 1982
    Date of Patent: October 15, 1991
    Assignee: Minnesota Mining and Manufacturing Company
    Inventors: James R. Husman, James N. Kellen, Rebecca E. McCluney, Michael L. Tumey
