  • Novel propylene polymerization process
    Patent number: 4847340
    Abstract: A novel highly efficient process is disclosed for the production of substantially amorphous ethylene-propylene copolymers. The polymers have properties which make them applicable for use, e.g., as hot melt adhesives, as blending components in roofing materials, and as cable and wire flooding agents.
    Type: Grant
    Filed: February 16, 1988
    Date of Patent: July 11, 1989
    Assignee: Rexene Products Company
    Inventors: George C. Allen, Brian J. Pellon, Michael P. Hughes
  • Novel propylene polymerization process
    Patent number: 4736002
    Abstract: A novel process for the production of substantially amorphous interpolymers of propylene, ethylene and optionally a third alpha-olefin comonomer having between 4 and 8 carbon atoms per molecule is disclosed. The polymers have properties which make them applicable for use, e.g., as hot melt adhesives and as blending components in roofing materials.
    Type: Grant
    Filed: June 30, 1986
    Date of Patent: April 5, 1988
    Assignee: El Paso Products Company
    Inventors: George C. Allen, Brian J. Pellon, Michael P. Hughes
  • Removal of sulfur compounds from pentane
    Patent number: 4540842
    Abstract: Pentane derived from fractionation of sulfur-containing natural gasoline is desulfurized to low levels of sulfur, e.g., 1 ppm or below, in a process comprised of contacting the pentane in a first zone with molecular sieve adsorbent to remove dimethylsulfide and then in a second zone with activated carbon to remove carbon disulfide.
    Type: Grant
