Title:
HYBRID SUPPORTED METALLOCENE CATALYST, METHOD FOR PREPARING THE SAME, AND PROCESS FOR PREPARING POLYOLEFIN USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2013/133595
Kind Code:
A1
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.
