Abstract:
The present invention relates to a supported hybrid catalyst and a method for preparing olefin polymer using the same. Using the supported hybrid catalyst, olefin polymer that maintains excellent mechanical strength of olefin polymer polymerized with the existing metallocene catalyst, but exhibits remarkably improved processibility compared to the existing olefin polymer, can be provided.

Claim (Index 11):
