Abstract: The present disclosure relates to a method for preparing a polyolefin using a supported hybrid metallocene catalyst. According to the present disclosure, a polyolefin having a narrow molecular weight distribution can be prepared very effectively by introducing a cocatalyst in an optimum conent in the presence of a supported hybrid metallocene catalyst containing two or more metallocene compounds having a specific chemical structure. The polyolefin prepared according to the present disclosure exhibits excellent uniformity in chlorine distribution in polyolefin during chlorination, thereby significantly improving elongation of the chlorinated polyolefin, compatibility with PVC and impact reinforcing performance. Thus, it exhibits excellent chemical resistance, weather resistance, flame retardancy, processability and impact strength reinforcing effect, and can be suitably applied as an impact reinforcing agent for PVC pipes and window profiles.

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.
