Claim Text:
1. A method of preparing a polyolefin using a supported hybrid catalyst in which at least two different transition metal catalyst compounds are supported in one support, wherein the polyolefin has 1) a density in the range of 0.93 to 0.97 g/cm in the Equation 1, the “Content of SCB at the high molecular weight side” means the content of the SCB (the number of branches/1000 carbon atoms) included in a polymer chain having a molecular weight of Mw of the polyolefin or more and 1.3×Mw or less, and the “Content of SCB at the low molecular weight side” means the content of the SCB (the number of branches/1000 carbon atoms) included in a polymer chain having a molecular weight of 0.7×Mw of the polyolefin or more and less than Mw, wherein a first transition metal catalyst compound, which is one of the transition metal catalyst compounds, is selected from the group consisting of [t-Bu-O—(CH wherein R7s are the same as or different from each other, and are each independently selected from hydrogen and a methyl radical; and Q5 and Q6 are the same as or different from each other, and are each independently selected from a methyl radical and a chloride radical.
