<p>The present invention relates to a metallocene compound and the olefin polymerization using the same, particularly to a metallocene compound and the olefin polymerization using this compound on which supported catalysts are easily prepared by the reaction of the ligand containing - (CR12)a-O-SiRbYc ligand (wherein each Y, which can be the same as or different from other Y, is a hydrogen, halogen, alkoxy, aryloxy, amide, or silyloxy radical, each R1, which can be the same as or different from other R1, is a hydrogen radical, or an alkyl, cycloalkyl, aryl, alkenyl, alkylaryl, arylalkyl, or arylalkenyl radical having from 1 to 40 carbon atoms, each R, which can be the same as or different from other R, is an alkyl, cycloalkyl, aryl, alkenyl, alkylaryl, arylalkyl, or arylalkenyl radical having from 1 to 40 carbon atoms, a is an integral number from 1 to 40, c is 1, 2, or 3, and the sum of b and c is 3) with a support. Furthermore, the present invention relates to a supported metallocene catalyst using this metallocene compound and the olefin polymerization using the same. The metallocene compounds in this invention have superior characteristics in the preparation of supported catalyst due to the high reactivity with the support and minimal side reactions during the anchoring process. In addition, the olefin polymerization process employing the supported catalyst in this invention proceeds without fouling in the reactor, and the morphology and bulk density of the polymer produced are better than that produced by the conventional method.</p> |
