  • Publication number: 20240101728
    Abstract: A hybrid catalyst composition containing a heterogeneous transition metal compound, a catalyst for olefin polymerization containing the heterogeneous transition metal compound, and a method for preparing an olefin-based polymer in which generation of a gel is suppressed using the catalyst are disclosed. The method for preparing an olefin-based polymer can provide an olefin-based polymer in which non-uniformity of the olefin-based polymer, and in particular, generation of a gel is suppressed.

  • Publication number: 20220025077
    Abstract: The present invention relates to a process for preparing a catalyst for olefin polymerization. Specifically, the present invention relates to a process for preparing a supported metallocene catalyst capable of producing a polyolefin in which the formation of gels is suppressed. In the process for preparing a supported metallocene catalyst according to an embodiment of the present invention, it is treated with a metallic stearate after a transition metal compound has been supported, which suppresses the formation of a macromolecular polyolefin. Thus, a polyolefin with minimal gel formation can be prepared.
