Zusammenfassung:A hybrid supported metallocene catalyst is provided to offer excellent catalyst activation in an olifin polymerization reaction, and to produce a polymer with excellent particle shape and bulk density. A hybrid supported metallocene catalyst contains a carrier in which the surface is processed by an ionic compound denoted by chemical formula 1 and a co-catalyst, a first metallocene compound denoted by chemical formula 2, and a second metallocene compound denoted by chemical formula 3. A production method of a hybrid supported metallocene catalyst comprises a step of processing the ionic compound and the co-catalyst on the carrier; and depositing the first and second metallocene compounds on the carrier.
