Patent number: 8008415Abstract: The present invention relates to a norbornene polymer that comprises a norbornene monomer having a photoreactive functional group, and a method of manufacturing the same. The norbornene polymer comprises at least 50 mol % of exo isomers among the norbornene monomers having the photoreactive functional group. Since the norbornene polymer according to the present invention comprises at least 50 mol % of exo isomers among the norbornene monomers having the photoreactive functional group, a molecular weight is significantly increased while the yield is not reduced during the manufacturing of the polymer. In views of the three dimensional structure, stability is ensured because the polymer has a planar structure in which the photoreactive groups between the molecules are close to each other. Therefore, the distance between the photoreactive groups is reduced, thus increasing the photoreaction rate.Type: GrantFiled: March 21, 2008Date of Patent: August 30, 2011Assignee: LG Chem, Ltd.Inventors: Heon Kim, Sung-Ho Chun, Hye-Young Jung, Dai-Seung Choi, Kyoung-Hoon Kim, Jong-Chan Kim

Patent number: 7858718Abstract: Catalysts useful for polymerizing olefins are disclosed. The catalysts comprise an activator and a Group 4 metal complex that incorporates a dianionic, tridentate 2-aryl-8-anilinoquinoline ligand. In one aspect, supported catalysts are prepared by first combining a boron compound having Lewis acidity with excess alumoxane to produce an activator mixture, followed by combining the activator mixture with a support and the tridentate, dianionic Group 4 metal complex. The catalysts are easy to synthesize, support, and activate, and they enable facile production of high-molecular-weight polyolefins.Type: GrantFiled: July 22, 2009Date of Patent: December 28, 2010Assignee: Equistar Chemicals, LPInventors: Sandor Nagy, Linda N.
