  • Polyester compositions containing a phthalimide
    Patent number: 4639480
    Abstract: Disclosed are compositions of polyethylene terephthalate and certain N-substituted phthalimide plasticizers, particularly polyethylene terephthalate molding compositions additionally containing a reinforcing agent and a nucleating agent.
    Type: Grant
    Filed: May 17, 1985
    Date of Patent: January 27, 1987
    Assignee: Monsanto Company
    Inventors: Gail H. Birum, Thomas C. Mathis, Richard D. Stolk
  • Novel compounds and their use in elastomer-containing compositions
    Patent number: 4404311
    Abstract: Elastomeric polymers are rendered more tractable, thereby decreasing the amount of vehicle or heat required for vehicle- or melt-deposition, while resulting in very little or no loss of strength of the polymer, by the use of at least one compound comprising at least three hydrocarbon rings including at least one aromatic ring and, in most embodiments, at least one saturated ring free to rotate independently of at least one aromatic ring in the molecule of that compound. Compositions comprising an elastomeric polymer and at least one such compound are especially attractive for use in solvent, latex and/or hot melt adhesive compositions.
    Type: Grant
    Filed: September 24, 1982
    Date of Patent: September 13, 1983
    Assignee: Monsanto Company
    Inventors: Thomas C. Mathis, Albert W. Morgan
