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.

imidazolium ring leads to a new generation of imidazolium‐based ionicliquids (TAAILs: tunablearylalkylionicliquids; see charge distribution of the methoxyphenyl methyl derivative). Electronic interaction between the aromatic substituent and the imidazolium core allows the properties of these species to be tuned more precisely than is possible for currently available ionicliquids.
