The present disclosure relates to a method of preparing a supported hybrid metallocene catalyst, and in particular to a method wherein a first metallocene compound is supported, and a cocatalyst is supported by a split input method, wherein the first added at 100°C to 150°C A portion of the cocatalyst, followed by adding the remaining portion at a temperature of -5°C to 40°C, and then supporting the second metallocene compound. Thus, the present invention improves the loading rate of the cocatalyst in the supported catalyst and maintains its high catalytic activity. Therefore, the present disclosure can improve the morphology (reduced fines) and bulk density of the produced polymer, and improve the settling efficiency, and can also be effectively used for the preparation of polyolefins that exhibit increased molecular weight distribution and have improved processability . |
