  • Substituted metallocene catalysts
    Patent number: 9458254
    Abstract: This invention relates to novel bridged a hafnium transition metal metallocene catalyst compounds having two indenyl ligands substituted at the 4 positions with a C1 to C10 alkyl, where the 3 positions are hydrogen (assuming the bridge position is counted as the one position) and the bridging atom is carbon or silicon which is incorporated into a cyclic group comprising 3, 4, 5, or 6 silicon and/or carbon atoms that make up the cyclic ring.
    Type: Grant
    Filed: July 8, 2014
    Date of Patent: October 4, 2016
    Assignee: ExxonMobil Chemical Patents Inc.
    Inventors: Jo Ann M. Canich, Ilya S. Borisov, Arkady K. Golenishchev, Georgy P. Goryunov, Dmitry V. Uborsky, Pavel S. Kulyabin, Dmitry S. Kononovich, Vyatcheslav V. Izmer, Alexander Z. Voskoboynikov
  • Pyridyldiamide metal catalysts and processes to produce polyolefins
    Patent number: 9321858
    Abstract: Disclosed are new classes of pyridyldiamide catalyst components useful in olefin polymerization, an example of which includes: wherein M is a hafnium or zirconium; R1 and R11 are selected from phenyl and substituted phenyl, wherein the substitutions are selected from C1 to C5 hydrocarbyls, preferably C2 to C4 hydrocarbyls, and can reside in any of the ortho, meta, para positions on the phenyl ring; R2? and R2? are selected independently from hydrogen and C1 to C6 hydrocarbyls, preferably hydrogen; R10 is a hydrocarbyl bridging group; R3, R4, and R5 are independently selected from hydrogen, hydrocarbyls, and substituted hydrocarbyls; and R6, R7, R8, and R9 are independently selected from hydrogen, hydrocarbyls, and substituted hydrocarbyls; wherein R6 and R7 form an aromatic ring or R7 is hydrogen and R6 is selected from methyl, ethyl, propyl, isopropyl, butyl, sec-butyl, and tert-butyl, preferably methyl.
