    摘要： The present invention relates to a preparation method of a highly active supported metallocene catalyst which can prepare a polyolefin of high bulk density. More specifically, the present invention provides a method of preparing the supported metallocene catalyst in which one or more metallocene catalysts are loaded on the silica carrier of which the inside is penetrated by more cocatalyst than the prior art and the outside is attached with a substantial amount of the cocatalyst. The catalyst according to the present invention can prepare a polyolefin polymer with improved bulk density and efficiency while maintaining its highly active catalytic characteristic.

    摘要： The present disclosure relates to a method for preparing a supported hybrid metallocene catalyst, and the catalyst is prepared by supporting a first metallocene compound, supporting a cocatalyst by a separate-input method in which primarily adding a part at 100 °C to 150 °C and secondarily adding the rest at -5 °C to 40 °C, and then supporting a second metallocene compound, thereby improving a supporting rate of the cocatalyst in the supported catalyst and maintaining high catalytic activity. Therefore, the present disclosure can effectively prepare a polyolefin with improved processability which exhibits increased molecular weight distribution while having high morphology (reduced fine powder), high bulk density and improved settling efficiency.
