  • Method of utilizing polyacrylic hot-melt adhesives
    Patent number: 4152189
    Abstract: Novel polyacrylic hot melt adhesives prepared by blending a polymer having a Tg of -85.degree. to 0.degree. C. with a polymer having a Tg of 20.degree. to 150.degree. C. are disclosed.
    Type: Grant

    Inventors: John D. Guerin, Thomas W. Hutton, John J. Miller, Richard E. Zdanowski
  • Internally plasticized polymer latex
    Patent number: 4150005
    Abstract: This invention relates to a latex of internally plasticized polymer particles, low in viscosity although high in hydrophilic components and film forming at temperatures below the calculated Tg of the polymer. The polymer may be prepared by a multistage emulsion polymerization process. The first stage is highly water-swellable or water-soluble. The principal second or later stage is less hydrophilic and of higher Tg than the first stage and is polymerized in the emulsion in the presence of the first stage.

  • Backing-free massive thickness pressure sensitive adhesive sheet and bonding rigid objects to larger surfaces
    Patent number: 4145465
    Abstract: In manufacturing industrial products such as automobiles, it is known to adhere rigid solid objects such as emblems, the manufacturer's name, body trim, and so forth to the automobile body by means of a relatively thick sheet of resilient foamed plastic such as polyurethane, for example, 30 one thousands of an inch (30 mils) in thickness, coated on each face with a pressure sensitive adhesive. This provides a cushioning effect to take care of the wide variations in the uniformity of the emblems and further provides a cushion so that when the emblem is struck a blow it does not pop off as would be the case with a thin adhesive layer absent the foam layer.
