  • Patent number: 5416127
    Abstract: This invention is a hot melt pressure sensitive adhesive formed by copolymerizing acrylic, or a combination of acrylic and vinyl, monomers with the functional monomer, 1-(1-isocyanato-1-methyl ethyl)-3-(1-methyl ethenyl)benzene m-TMI, to give a saturated polymer with pendant vinyl groups that are crosslinked by UV or EB radiation.
    Type: Grant
    Filed: January 26, 1994
    Date of Patent: May 16, 1995
    Assignee: National Starch and Chemical Investment Holding Corporation
    Inventors: Rama Chandran, Roopram Ramharack, Irwin J. Davis, John C. Leighton
  • Patent number: 5037700
    Abstract: Flexible laminates are prepared using a room temperature curable, water-borne laminating adhesive. The adhesive consists essentially of a copolymer emulsion of an alkyl acrylate, alkyl methacrylate, styrene or vinyl ester, or mixtures thereof, and an ethylenically unsaturated carboxylic acid, and optional selected comonomers, combined with an epoxy resin emulsion and a polyfunctional amine. The flexible laminates are characterized by rapid room temperature curing, high bond strength, superior heat resistance and chemical and water resistance.
    Type: Grant

    Date of Patent: August 6, 1991
    Assignee: National Starch and Chemical Investment Holding Corporation
    Inventor: Irwin J. Davis
  • Patent number: 4728572
    Abstract: Hot melt adhesive compositions prepared from styrene-isoprene-styrene block copolymers, a low softening point highly aliphatic resin and a metallic salt of a fatty acid exhibit a superior balance of properties in that they adhere well to a variety of substrates yet can be readily and cleanly removed when desired.
    Type: Grant

  • Patent number: 4485200
    Abstract: Conventional carboxylated neoprene latex adhesives are improved with respect to their metal adhesion, heat and water resistance and bonding range by the addition thereto of an epoxy resin, preferably an epoxy resin prepared by the reaction of para-aminophenol with epichlorohydrin.
    Type: Grant
    Filed: February 3, 1982
    Date of Patent: November 27, 1984
    Assignee: National Starch and Chemical Corporation
    Inventors: Witold Perlinski, Irwin J. Davis, John F. Romanick
  • Patent number: 4463110
    Abstract: The metal adhesion and heat and water resistance of conventional neoprene latex adhesives are improved by the addition thereto of a polyfunctional amine and an epoxy resin wherein for every 100 parts by weight of dry neoprene, the epoxy is added in an amount of 10-40 parts and the amine is added in an amount sufficient to provide 50-150% of the stoichiometric amount required to cure the epoxy.
    Type: Grant
    Filed: February 18, 1982
    Date of Patent: July 31, 1984
    Assignee: National Starch and Chemical Corporation
    Inventors: Witold Perlinski, Irwin J. Davis, John F. Romanick
  • Patent number: 4342843
    Abstract: The metal adhesion and heat and water resistance of conventional neoprene latex adhesives are improved by the addition thereto of a polyamine and an epoxy resin wherein for every 100 parts by weight of dry neoprene, the epoxy is added in an amount of 10-40 parts and the amine is added in an amount sufficient to provide 50-150% of the stoichiometric amount required to cure the epoxy.
    Type: Grant

  • Patent number: 4069123
    Abstract: Improved pressure sensitive adhesive compositions based on acrylate ester polymers and the substrates coated therewith. The improved adhesive and cohesive properties result from the addition to the polymer of specified quinone ultraviolet sensitizers and the subsequent crosslinking thereof by exposure to an ultraviolet source.
