Abstract: Provided are a catalyst for olefin polymerization including a hybrid catalyst composition and an olefin-based polymer prepared therefrom. The hybrid metallocene catalyst allows preparation of an olefin polymer having a broad molecular weight distribution and excellent high-speed processability. In addition, an olefin-based polymer prepared in the presence of the hybrid catalyst has a broad molecular weight distribution and excellent high-speed processability.

Abstract: Provided are a method for preparing an olefin-based polymer and an olefin-based polymer produced using the same. The method for preparing an olefin-based polymer according to an exemplary embodiment may adjust processability of the olefin-based polymer produced using the method by a polymerization temperature. In addition, the method for preparing an olefin-based polymer according to the exemplary embodiment may adjust drop impact strength of a finally obtained film by a polymerization temperature.
