Patent number: 6509288Abstract: Catalyst system suitable for preparing substantially terminally unsaturated atactic polymers or copolymers of &agr;-olefins having a molecular weight (Mn) in the range 200-500,000. The catalyst system includes a metallocene of the formula: [RmCpH(5-m)][RnCpH(5-n)]M(Z)Y wherein CpH is a cyclopentadienyl ligand, each R represents an alkyl or an aryl substituent on the CpH ligand or two R's may be joined together to form a ring, or the Rs in each CpH group when taken together represents an Si or C bridging group linking two CpH groups wherein the Si or C group may itself be substituted by hydrogen atoms or C1-C3 alkyl groups, M is a metal selected from hafnium, zirconium and titanium, Z is selected from a hydrogen atom, a trifluoromethane sulphonate, an alkyl and an aryl group, Y is selected from a, 1,3-diketonate and a &bgr;-ketoester arion, and each of m and n is same or different and has a value from 0 to 5.Type: GrantFiled: November 19, 1999Date of Patent: January 21, 2003Assignee: BP Chemicals LimitedInventors: Birgit Angelika Dorer, Christopher Sharp, Richard Henry Weatherhead

Patent number: 6455649Abstract: A catalyst comprising an organoaluminum compound and a vanadium chelate compound having the lability to cause olefins to undergo living coordination polymerization is contacted with a terminal diolefin to obtain a catalyst for living polymer production. When the above contact is:conducted in the presence of a cycloolefin or an internal olefin, the yield of a living polymer can be improved. By modifying all ends of the living polymer obtained, a telechelic olefin polymer is obtained in which all the polymer chains are modified with functional groups.Type: GrantFiled: March 3, 2000Date of Patent: September 24, 2002Assignees: Japan as represented by Director General of Agency of Industrial Science and Technology, Japan Chemical Innovation InstituteInventors: Yoshihumi Fukui, Masahide Murata, Kazuo Soga, Michihiko Asai, Yasuzou Suzuki, Akira Miyazawa, Kenji Tsuchihara, Hiroyuki Ozaki, Masanao Kawabe, Naoya Kishi
