    Inventors: Abraham A. Smaardijk, Arris H. Kramer
  • Polymerization process
    Patent number: 4948870
    Abstract: Linear alternating polymers of carbon monoxide and at least one ethylenically unsaturated hydrocarbon are produced in the presence of novel catalyst compositions formed from a palladium salt, the anion of a non-hydrohalogenic acid having a pKa less than 2 and a bidentate ligand having one atom of phosphorous and one atom of sulfur or selenium.
    Type: Grant
    Filed: May 12, 1989
    Date of Patent: August 14, 1990
    Assignee: Shell Oil Company
    Inventors: Johannes Van Doorn, Arris H. Kramer, Johannes J. Maria Snel
  • Polymer of dicyclopentadiene and a process for preparation
    Patent number: 4810762
    Abstract: The invention is a process for preparing a polymer which comprises contacting dicyclopentadiene with a catalyst comprising a phenolic substituted tungsten halide and a trialkyltin hydride or triphenyltin hydride and recovering said polymer. The invention is also a polymer of dicyclopentadiene as prepared in the process of the invention and a catalyst used in the process of the invention to prepare said polymer.

  • Resin compositions
    Patent number: H1110
    Abstract: Novel thermosetting resin compositions comprise (1) a polyalcohol produced by reduction of a low molecular weight linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon and (2) a polyfunctional curing agent. The compositions are cured upon application of heat to cured, crosslinked compositions useful as coatings.
