  • Polymerization catalyst composition
    Patent number: 7176158
    Abstract: Copolymerization of Ni(H) or Co(II) acenaphthene diimine complexes containing olefinic substituents on aryl groups in the presence of a free radical initiator results in polymerized late transition metal catalysts which can be used for olefin polymerization or oligomerization. These catalysts have high catalyst activity for olefin polymerization or oligomerization.
    Type: Grant
    Filed: October 24, 2003
    Date of Patent: February 13, 2007
    Assignee: ExxonMobil Chemical Patents Inc.
    Inventors: Stanley Wai-Yan Chow, Guo-Xin Jin, Zerong Lin, Robert J. Wittenbrink, Dao Zhang
  • Polymerized catalyst composition II
    Patent number: 7119155
    Abstract: Copolymerization of Ni(II) phenol imine complexes containing olefinic substituents on aryl groups with styrene in the presence of a radical initiator results in polymerized late transition metal catalysts which can be used for olefin polymerization or oligomerization. These catalysts have high catalyst activity for olefin polymerization or oligomerization.
