摘要： The present invention relates to an olefin polymer and a preparation method thereof. The olefin polymer exhibits excellent mechanical strength and high processability, and thus is expected to be utilized as a material for various products. Particularly, the olefin polymer can be stably produced into films by a melt-blowing process and thus is expected to be usefully used as a material for products prepared by a melt-blowing process.
