    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： A supported metallocene catalyst can include a silica-based carrier and an aluminum alkyl halide, a cocatalyst compound, and a metallocene compound supported in the silica-based carrier. The aluminum alkyl halide is supported at higher rate on the surface of the silica-based carrier than inside the pores, and the cocatalyst compound is supported at higher rate inside the pores of the silica-based carrier than on the surface of the silica-based carrier. Such a supported metallocene catalyst can be prepared by: (i) supporting an aluminum alkyl halide in a silica-based carrier; (ii) supporting a cocatalyst compound in the silica-based carrier in which the aluminum alkyl halide is supported; and (iii) supporting a metallocene compound in the carrier in which the aluminum alkyl halide and the cocatalyst compound are supported. Such a supported metallocene catalyst can be used to polymerize polyolefins with excellent activity and polyolefin with a uniform powder morphology.
