Patent number: 7273912Abstract: Supported catalyst systems are provided comprising (a) a transition metal compound, (b) a non aluminoxane activator comprising, and (c) a support material comprising an inorganic metal oxide, inorganic metal halide or polymeric material or mixtures thereof characterised in that the support material has been pretreated with an SO4 containing compound. The preferred transition metal compounds are metallocenes and the SO4 containing compound is typically sulphuric acid. The supported catalyst systems show improved activity and also may reduce fouling in gas phase fluidised bed processes.Type: GrantFiled: December 3, 2003Date of Patent: September 25, 2007Assignee: Innovene Europe LimitedInventors: Grant Berent Jacobsen, Brian Stephen Kimberley, Claudine Viviane Lalanne-Magne, Sergio Mastroianni

Patent number: 7273914Abstract: Methods for making polyolefins are disclosed. One method comprises polymerizing an olefin in the presence of a catalyst system comprising a single-site complex, an agglomerated metal oxide/clay support-activator, and an ionic borate. Including an ionic borate with the support-activator provides an unexpected boost in catalyst activity and gives polyolefins with high molecular weight and improved comonomer incorporation. In another method of the invention, an olefin is polymerized in the presence of an indenoindolyl metal alkylated complex and an agglomerated metal oxide/clay support-activator. Use of alkylated indenoindolyl complexes with the support-activators provides improved activity compared with metal halides.Type: GrantFiled: August 3, 2005Date of Patent: September 25, 2007Assignee: Equistar Chemicals, LPInventors: Shaotian Wang, Barbara M. Tsuie, Mark P. Mack, Edward S. Vargas, Debra L. Beran

Patent number: 7273915Abstract: A crosslinkable resin composition is provided which can be a forming material having excellent adhesion to metals and excellent heat resistance. The crosslinkable resin composition comprises; a cycloolefin resin (A) obtained through metathesis polymerization of a cycloolefin monomer in the presence of a compound having two or more vinyl groups in the molecule, and a radical generating agent (B). A crosslinked resin molded product is obtained by crosslinking such a crosslinkable resin composition through heating.Type: GrantFiled: August 13, 2004Date of Patent: September 25, 2007Assignee: Zeon CorporationInventor: Tomoo Sugawara

Patent number: 7273916Abstract: A cross-linkable and cross-linked organosilicon polymer which is prepared from a mixture of a reactive polysiloxane resin having both reactive carbon-carbon double bonds and silicone-hydrogen groups, characterized by alternating structures of polycyclic polyene residue and cyclic (or tetrahedral) polysiloxane residue, and either vinyl terminated fluorine-containing polysiloxane or vinyl terminated phenyl-substituted siloxane. In an alternative embodiment, the polymer comprises a mixture of vinyl terminated phenyl-substituted polysiloxane and vinyl functional fluorosilicone elastomer with the cross-linkable and cross linked organosilicon polymer.Type: GrantFiled: July 29, 2004Date of Patent: September 25, 2007Assignee: National Starch and Chemical Investment Holding CorporationInventors: Elizabeth M. Walker, Jiazhong Luo, Rose Ann Schultz, Katharine Louise Pearce
