Abstract:
The present disclosure relates to a supported hybrid metallocene catalyst and a method for preparing a polyolefin using the same. When the supported hybrid metallocene catalyst according to the present disclosure is used, a polyolefin with a multimodal molecular weight distribution and excellent environmental stress crack resistance can be prepared.

Claim (Index 9):
The supported hybrid metallocene catalyst of  claim 1 ,\n wherein the cocatalyst comprises at least one selected from the group consisting of a first cocatalyst represented by the following Chemical Formula 4 and a second cocatalyst represented by the following Chemical Formula 5:\n \u2014[Al(R 28 )\u2014O] k \u2014\u2003\u2003[CHEMICAL FORMULA 4] \n in Chemical Formula 4, each R 28  is the same as or different from each other, and each is independently a halogen, or a C1 to C20 hydrocarbyl group substituted or unsubstituted with a halogen, and k is an integer of 2 or more,\n T + [BG 4 ] \u2212 \u2003\u2003[CHEMICAL FORMULA 5] \n in Chemical Formula 5, T +  is a polyatomic ion having a valence of +1, B is boron in a +3 oxidation state, and each G is independently selected from the group consisting of hydride, dialkylamido, halide, alkoxide, aryloxide, hydrocarbyl, halocarbyl, and halo-substituted hydrocarbyl, and G has 20 or fewer carbons, provided that G is a halide in one or fewer positions.
