Abstract
Provided are a hybrid supported metallocene catalyst, a method for preparing the same, and a process for preparing an olefin polymer using the same, and more particular, a hybrid supported metallocene catalyst characterized in that two kinds of metallocene compounds containing a new cyclopenta[b]fluorenyl transition metal compound are supported on an inorganic or organic porous carrier surface-treated with an ionic compound and a co-catalyst, a method for preparing the same, and a process for preparing an olefin polymer using the hybrid supported metallocene catalyst.
