Abstract: The present disclosure relates to a novel metallocene compound. The metallocene compound according to the present disclosure may be used for the preparation of an olefin-based polymer, may have excellent ability, and may produce an olefin-based polymer having a relatively high molecular weight compared with the case of using a catalyst composition having a similar structure due to the structural and electrical steric hindrance effect.

Abstract: The present invention relates to a hybrid supported metallocene catalyst. More specifically, the present invention relates to a hybrid supported metallocene catalyst using two or more different types or more of metallocene compounds, among which one type of the metallocene compounds shows a high polymerization activity even when it is supported, and thus the catalyst has an excellent activity and can be utilized in the polymerization of olefinic polymers having ultra-high molecular weight. Based on the hybrid supported metallocene catalyst of the present invention, an olefinic polymer having high molecular weight and the desired physical property can be prepared.

Abstract: The present invention relates to a novel metallocene compound, a catalyst composition including the same, and a method of preparing an olefinic polymer by using the same. The metallocene compound according to the present invention and the catalyst composition comprising the same can be used for producing olefinic polymers, have outstanding polymerizing ability, and can produce olefinic polymers of ultra high molecular weight. In particular, when the metallocene compound according to the present invention is employed, an olefinic polymer of ultra high molecular weight can be obtained because it shows high polymerization activity even when it is supported on a carrier and maintains high activity even in the presence of hydrogen because of its low hydrogen reactivity.
