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.
提供了一种混合支撑的金属茂嗪催化剂,其制备方法以及使用该催化剂制备烯烃聚合物的方法。具体而言,该混合支撑的金属茂嗪催化剂的特点在于将两种含有新的环戊二十碳五烯基过渡金属化合物的茂嗪化合物支撑在经离子化合物和共催化剂处理的无机或有机多孔载体表面上,以及其制备方法和使用该混合支撑的金属茂嗪催化剂制备烯烃聚合物的方法。
