METALLOCENE COMPOUND, CATALYST COMPOSITION INCLUDING THE SAME, AND OLEFIN POLYMERIZATION PROCESS USING THE SAME

摘要

PURPOSE: A metallocene compound for preparing olefin polymers or copolymers by high polymerization activity is provided to constantly maintain polymerization activity and to ensure excellent catalytic activity. CONSTITUTION: A metallocene compound is denoted by chemical formula 1((4HInd)(Cp')MX_2). A metallocenen catalytic composition contains the metallocene compound and an activator. The activator includes alkyl aluminoxane, organic aluminum compound, bulky alipathic fluorine compounds, modified clay, or Lewis acid inorganic oxide. The metallocene catalytic composition further contains metallocene compound and activator-supported organic or inorganic carriers. A method for polymerizing olefin comprises a step of polymerizing one or more olefin under the presence of the metallocene compounds.
