TRANSITION METAL CATALYST SYSTEM WITH EXCELLENT COPOLYMERIZATION AND PREPARATION METHOD OF ETHYLENE HOMOPOLYMER OR COPOLYMER OF ETHYLENE AND ?-OLEFIN USING SAME |
摘要 |
<p>The present invention relates a homogeneous catalyst system for preparation of an ethylene homopolymer or a copolymer of ethylene and a-olefin, and more specifically to a group 4 transition metal compound in which a cyclopentadienyl derivate, substituted with alkyl at 3,4-positions centered around the group 4 transition metal compound, and an electron-donating substituent are crosslinked. In addition, the invention relates to a method for preparing a high molecular weight ethylene homopolymer or a copolymer of ethylene and a-olefin under a high temperature solution polymerization condition using a catalyst system comprising the transition metal compound and an aluminum compound co-catalyst or a boron compound co-catalyst, or a mixture thereof. According to the present invention, the catalyst has excellent thermal stability and copolymerization with a-olefin, and is thus effective in the preparation of an ethylene homopolymer or a copolymer of ethylene and a-olefin, which has various properties in commercial polymerization processes.</p> |
