Patents by Inventor Simon Kukes

Simon Kukes has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Olefin polymerization catalyst and polymerization process
    Patent number: 5276114
    Abstract: A method for making polymerization catalysts is disclosed which comprises contacting a soluble complex prepared from the combination of a metal dihalide and a transition metal compound with a particulate material comprising zirconium phosphate and then reacting the resulting mixture with an organoaluminum halide to produce a catalyst precursor. The catalyst precursor is then contacted with a halogen containing compound selected from halides of Groups IVA and VA to produce the catalyst. Novel catalysts prepared in accordance with the invention method, novel polymerization processes therewith and novel polymers having relatively high melt flow rates while retaining good mechanical strength are also disclosed.
    Type: Grant
    Filed: April 19, 1993
    Date of Patent: January 4, 1994
    Assignee: Phillips Petroleum Company
    Inventors: Gil Hawley, Max McDaniel, Simon Kukes

  • Olefin conversion
    Patent number: 4609769
    Abstract: Olefins are converted into other olefins having different numbers of carbon atoms by contact with a catalyst comprising a silica support containing tungsten oxide and a promoting amount of at least one titaniferous agent and activated under conditions suitable for the titaniferous agent to promote the activity of tungsten oxide and silica for the disproportionation and isomerization reaction.
