  • Polymer-modified asphalt with a crosslinking agent and methods of preparing
    Patent number: 8198350
    Abstract: Methods of preparing a cross-linked, polymer-modified asphalt is provided. The method involves adding a crosslinking agent to asphalt prior to the addition of a crosslinkable polymer and an acid. Asphalt prepared by the disclosed methods exhibit improved properties such as properties measured by the Multiple Stress Creep Recovery (MSCR) test.
    Type: Grant

  • Uintaite-derived toners and printing inks
    Patent number: 5378272
    Abstract: A composition useful in copying and printing is described. In one embodiment, the composition comprises a purified fraction of uintaite and a thermoplastic polymer. Preferably, the composition comprises a maltene-enriched fraction of uintaite derived by solvent extraction, a thermoplastic polymer and a colorant. In another embodiment, the present invention is an electrophotographic method comprising the steps of generating a latent electrostatic image; developing said latent image with a toner comprising a purified fraction of uintaite; and fixing said toner. The present invention is also a printing ink emulsion comprising a maltene-enriched fraction of uintaite.
