摘要：The present invention relates to a catalyst composition and a process for preparing an olefin polymer using the same. More specifically, the present invention relates to a novel catalyst composition comprising at least two types of catalysts and a process for preparing an olefin polymer having excellent heat resistance using the same. The present invention can provide an olefin polymer having excellent activity and high heat resistance, and also can control the values of density, heat resistance and melt index (MI) of the olefin polymer.
