Abstract: The present invention relates to a method for preparing a hybrid supported metallocene catalyst. More specifically, the present invention relates to a method for preparing a hybrid supported metallocene catalyst by using two or more different types of metallocene compounds. 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 obtained according to the preparation method 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.

Abstract: The present application relates to a method for quantitative analysis of a polymer structure. Specifically, the method may be carried out through steps of measuring rheological properties and/or molecular weight distribution of the arbitrarily selected polymer, setting a random value for the selected polymer and then predicting the rheological property and/or the molecular weight distribution of the polymer from the random value, and comparing the measured value with the predicted value to determine the value of the structural parameter of the polymer.
