Ian Douglas McKay 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).

  • Polyethylene film
    Patent number: 8829137
    Abstract: Polyethylene films having a good balance of optical and mechanical properties are disclosed. The films are derived from ethylene copolymer compositions made with a suitably substituted phosphinimine catalyst. The ethylene copolymers have very narrow molecular weight distributions and broadened comonomer distributions.
    Type: Grant
    Filed: February 27, 2012
    Date of Patent: September 9, 2014
    Assignee: Nova Chemicals (International) S.A.
    Inventors: Patrick Lam, Victoria Ker, Charles Ashton Garret Carter, Benjamin Milton Shaw, Cliff Robert Baar, Alexei Kazakov, Ian Douglas McKay, Dusan Jeremic
  • Supported polymerisation catalysts
    Patent number: 8536081
    Abstract: Supported catalyst system for the polymerization of olefins, having at least two different monocyclopentadienyl transition metal compounds, one or more activators including an ionic compound having (i) a cation and (ii) an anion having up to 100 non-hydrogen atoms and the anion containing at least one substituent comprising a moiety having an active hydrogen, and one or more support materials. The supported “mixed or dual site” catalyst systems having different monocyclopentadienyl catalysts when activated by specific ionic activators lead to catalyst systems showing an improved balance of properties which may be used to prepare LLDPE polymers having broad melt flow ratios.
    Type: Grant

  • Supported Polymerisation Catalysts
    Publication number: 20080139763
    Abstract: Supported catalyst systems for the polymerisation of olefins, comprise (a) at least two different monocyclopentadienyl transition metal compounds, (b) one or more activators comprising an ionic compound comprising (i) a cation and (ii) an anion having up to 100 non-hydrogen atoms and the anion containing at least one substituent comprising a moiety having an active hydrogen, and (c) one or more support materials. The, supported “mixed or dual site” catalyst systems comprising different monocyclopentadienyl catalysts when activated by specific ionic activators lead to catalyst systems showing an improved balance of properties which may be used to prepare LLDPE polymers having broad melt flow ratios.
