Patent number: 6239062Abstract: A constrained geometry single-site olefin polymerization catalyst is described. The catalyst comprises an activator and an organometallic compound that includes a Group 3 to 10 transition or lanthanide metal, M, and a multidentate ligand characterized by an indolyl group that is covalently linked to an amido group, wherein the indolyl group is &pgr;-bonded to M and the amido group is &sgr;-bonded to M. The indolyl-amido ligand is formed from readily available organic compounds and allows easy synthesis of a constrained geometry catalyst system.Type: GrantFiled: September 2, 1999Date of Patent: May 29, 2001Assignee: Equistar Chemicals, L.P.Inventor: Leonard V.

Patent number: 6218332Abstract: The (polyfluoroaryl)fluoroanions of aluminum, gallium, and indium are novel weakly coordinating anions which are highly fluorinated. (Polyfluoroaryl)fluoroanions of one such type contain at least one ring substituent other than fluorine. These (polyfluoroaryl)fluoroanions of aluminum, gallium, and indium have greater solubility in organic solvents, or have a coordinative ability essentially equal to or less than that of the corresponding (polyfluoroaryl)fluoroanion of aluminum, gallium, or indium in which the substituent is replaced by fluorine. Another type of new (polyfluoroaryl)fluoroanion of aluminum, gallium, and indium have 1-3 perfluorinated fused ring groups and 2-0 perfluorophenyl groups.Type: GrantFiled: August 8, 2000Date of Patent: April 17, 2001Assignee: Northwestern UniversityInventors: Tobin J. Marks, You-Xian Chen

Patent number: 6197713Abstract: The present invention is directed to a process for the preparation of a gel-free hydrocarbon solution containing a lanthanide rare earth series compound by dissolving or synthesizing a lanthanide compound in an inert hydrocarbon solvent with a Lewis acid in an amount sufficient to prevent formation of highly viscous solutions. The present invention is also directed to the use of the gel-free Ln solutions formed by the recited process as co-catalysts for the polymerization of dienes. The Lewis acid is a group 2, 12, 13, 14 or 15 halide or organohalide, or a transition metal halide, excluding aluminum trialkyls.Type: GrantFiled: December 19, 1997Date of Patent: March 6, 2001Assignee: Bridgestone CorporationInventor: Thomas J.
