Publication number: 20030216249Abstract: A catalyst composition for preparing olefin polymers. The catalyst composition includes a metallocene compound and an activating cocatalyst. In the metallocene compound, two cyclopentadienyl groups are bridged by X (carbon, silicon, germanium or tin) in a ring structure. The bite angle &thgr; formed by the two cyclopentadienyl rings and X is equal to or greater than 100 degrees. The obtained olefin polymer has high cycloolefin conversion and a high glass transition temperature. In addition, the catalyst composition can still maintain relatively high activity at high temperature reaction conditions.Type: ApplicationFiled: June 12, 2003Publication date: November 20, 2003Applicant: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Jing-Cherng Tsai, Ming-Yuan Wu, Tung-Ying Hsieh, Yuh-Yuan Wei, Chao-Ying Yu

Publication number: 20030211933Abstract: A catalyst for olefinic polymer production comprises (a) a penta-coordinated, organic aluminium oxide compound, (b) an alkylating agent and (c) a compound of a transition metal of Group IV, V, VI or VIII of the Periodic Table. Olefins are homopolymerized or copolymerized in the presence of the catalyst for olefinic polymer production to produce olefinic polymers. The process does not require a promoter of methylaluminoxane, with which the problem is low solubility and low storage stability. Using therein the penta-coordinated, organic aluminium oxide compound which is relatively inexpensive and can be produced easily, the process realizes high-yield production of olefinic polymers.Type: ApplicationFiled: April 29, 2003Publication date: November 13, 2003Applicant: Idemitsu Kosan Co., Ltd.Inventors: Shinjiro Fujikawa, Harumi Nakashima, Satoshi Ikeuchi, Fumio Okuda, Toshiya Abiko
