  • Laminating construction adhesive compositions with improved performance
    Patent number: 6251213
    Abstract: Aqueous laminating construction adhesive compositions incorporating a one-part adhesive copolymer, the copolymer being a vinyl ester/acrylic copolymer containing from about 0.1% to about 20%, by weight based on copolymer weight, of a copolymerized polar monomer, the copolymer having a Tg from about 10° C. to about −35 C. are provided which exhibit a good balance of high temperature and ambient temperature adhesion performance in a one-part adhesive composition.
    Type: Grant
    Filed: April 30, 1993
    Date of Patent: June 26, 2001
    Assignee: Rohm and Haas Company
    Inventors: Benjamin Bartman, Kathleen Anne Hughes, Eric Karl Eisenhart, Joann Marie Eisenhart
  • Pressure sensitive hot melt adhesives
    Patent number: 4423182
    Abstract: This invention is directed to compositions useful as ionomeric hot melt pressure sensitive adhesive compositions. These compositions comprise a polymer containing carboxylic acid, a miscible metal salt, and an o-methoxy-substituted aryl acid. These compositions display low melt viscosity, simplifying application, as well as improved adhesive properties, especially shear resistance.

  • Amine crosslinked methacrolein copolymers for coatings, binders and adhesives
    Patent number: 4230772
    Abstract: Aqueous, solution or emulsion, and solvent based compositions comprising a crosslinked vinyl addition polymer having methacrylaldimine crosslinking groups are useful as coatings, binders and adhesives. The polymers are prepared from a crosslinkable composition comprising (A) a vinyl addition homopolymer or copolymer of methacrolein and (B) a compound having at least two amine-function groups selected from primary amine and primary amine-generating groups. A method of use is described in which crosslinking is at ambient temperatures.
