Abstract: The method for oligomerizing olefin according to the present disclosure is a method for oligomerizing olefin using an oligomerization catalyst system and includes deteriorating the activity of the oligomerization catalyst system by injecting a deactivator in a latter part of a multimerization reaction of olefin. The deactivator may include an additive for polymer containing at least one functional group selected from the group consisting of a hydroxyl group, an amine group and an amide group. According to the oligomerizing method, the isomer of 1-hexene and/or 1-octene and alpha-olefins with C10 to C40 may be decreased via the restraint of the additional side reaction of a product. Since the deactivator is an additive for enhancing the physical properties of a polymer, a separating process thereof is not required, thereby improving economic feasibility and productivity.

Abstract: Provided are a hybrid supported catalyst system and a method of preparing a polyolefin using the same. The hybrid supported catalyst system according to the present invention may be used to perform oligomerization and copolymerization of olefin monomers in a single reactor at the same time with high efficiency without a separate process of preparing alpha-olefin. Therefore, costs for preparing or purchasing comonomers which are expensive raw materials may be reduced, thereby reducing the production cost of a final product.

Abstract: Provided are a novel metallocene compound, a catalyst composition including the same, and a method of preparing an olefin-based polymer using the same. The metallocene compound according to the present invention or the catalyst composition including the same may be used for the preparation of an olefin-based polymer, may have excellent polymerization ability, and may produce an olefin-based polymer having a high molecular weight. In particular, when the metallocene compound according to the present invention is employed, an olefin-based polymer having a high molecular weight may be polymerized because the metallocene compound shows high polymerization activity even when it is supported on a support and maintains high activity even in the presence of hydrogen because of its low hydrogen reactivity.
