  • HYBRID CATALYST COMPOSITION, CATALYST COMPRISING SAME, AND METHOD FOR PREPARING OLEFIN-BASED POLYMER USING SAME
    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.

  • OLEFIN POLYMER AND PREPARATION METHOD THEREFOR
    Publication number: 20240084057
    Abstract: An olefin polymer and a preparation method for manufacturing the olefin polymer are disclosed. The olefin polymer has a high melting point and a high crystallization temperature, thus having excellent heat resistance. Therefore, the olefin polymer may be utilized in spout pouches for high-temperature liquid containers, or the like. The olefin polymer may have a density of 0.9 to 0.95 g/cm3, preferably 0.91 to 0.945 g/cm3, and satisfies the following Equations 1a and 2a: 224.02×d?86.257<Tm, and ??[Equation 1a] 219.64×d?95.767<Tc.
