摘要： The present invention relates to a method for preparing polyolefin that can easily and effectively prepare polyolefin having high molecular weight and various molecular weight distributions, which was difficult to prepare using the existing metallocene catalyst, and polyolefin prepared thereby. The method for preparing polyolefin comprises the step of polymerizing olefin monomers, in the presence of a metallocene supported catalyst wherein a metallocene compound having a specific chemical structure is supported in a carrier, and hydrogen gas.

摘要： The present invention relates to a hybrid supported metallocene catalyst and a polyolefin preparation method using the same. Using the hybrid supported metallocene catalyst can not only significantly reduce the amount of wax produced when polymerizing olefin monomers, but can also enhance the stress cracking resistance of the polyolefin that is prepared.

摘要： 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.
