Abstract
The present invention relates to a hybrid supported metallocene catalyst. More specifically, the present invention relates to a hybrid supported metallocene catalyst using two or more different types or more of metallocene compounds, among which one type of the metallocene compounds shows a high polymerization activity even when it is supported, and thus the catalyst has an excellent activity and can be utilized in the polymerization of olefinic polymers having ultra-high molecular weight. Based on the hybrid supported metallocene catalyst of the present invention, an olefinic polymer having high molecular weight and the desired physical property can be prepared.
