METALLOCENE COMPOUNDS, CATALYST COMPOSITION COMPRISING THE SAME, AND METHOD FOR PREPARATION OF OLEFIN-BASED POLYMER USING THE SAME

摘要

PURPOSE: A novel metallocene compound and a catalyst composition containing the same are provided to produce a block copolymer with high thermal resistance. CONSTITUTION: A metallocene compound is denoted by chemical formula 1. A catalyst composition contains the metallocene compound of chemical formula 1. The catalyst composition additionally contains one or more of cocatalyst compound of chemical formula 3(-[Al(R18)-O]_n-), 4(D(R18)_3) or 5([L-H]^+[ZA_4]^- or[L]^+[ZA_4]^-). An olefin polymer is prepared under the presence of the catalyst composition. A method for preparing the catalyst composition comprises: a step of contacting the metallocene compound of chemical formula 1 with the compound of chemical formula 3 or 4 to obtain a mixture; and a step of adding a compound of chemical formula 5.
