Patent number: 7148302Abstract: This invention is based upon the discovery that a catalyst system which is comprised of (a) palladium or a palladium compound and (b) a fluorinated alcohol is effective for polymerizing norbornene-functional monomers into polynorbornene-functional polymers. It has been further discovered that this catalyst system is more effective in polymerizing certain norbornene-functional monomers that are difficult to polymerize, such as norbornene ester monomers, than prior art catalyst systems. The activity of the catalyst systems of this invention can be further improved with respect to polymerizing some monomers by including a Lewis acid and/or a ligand, such as a phosphine or a carbene, in the system. In any case, the catalyst systems of this invention offer the advantage of being soluble in a wide variety of solvents, relatively inexpensive, and capable of polymerizing many norbornene-functional monomers that are difficult to polymerize with conventional catalyst systems.Type: GrantFiled: October 3, 2005Date of Patent: December 12, 2006Assignee: The Goodyear Tire & Rubber CompanyInventor: John-Henry Lipian

Publication number: 20010039241Abstract: Complexes of magnesium and titanium alkoxides useful as olefin polymerization procatalyst precursors, procatalysts containing the complexes, and their use as a catalyst component for the polymerization of olefin monomers are disclosed. The complexes are prepared by reacting a magnesium alkoxide and a titanium alkoxide in the presence of a clipping agent to form a solid complex. The solid complex then can be used to form a procatalyst by contacting it with a halogenating agent, optionally a tetravalent titanium halide, and optionally an electron donor. The procatalyst then can be converted to an olefin polymerization catalyst by contacting it with a cocatalyst and optionally a selectivity control agent.Type: ApplicationFiled: June 20, 2001Publication date: November 8, 2001Inventor: Robert Charles Job
