The present invention relates to a process for producing a hybrid supported metallocene catalyst, a hybrid supported metallocene catalyst prepared by the process, and a process for producing a polyolefin using the same. According to the method for preparing a mixed supported metallocene catalyst of the present invention, aluminoxane can be obtained by using an alkylaluminum and a borate compound instead of expensive aluminoxane, which is mainly used for activating the supported metallocene catalyst, It is possible to maximize the catalytic activity in olefin polymerization without using it and to obtain a polyolefin having a high molecular weight. |
