Abstract:
The present disclosure provides a method for preparing a supported hybrid metallocene catalyst which can be used to prepare a polyolefin, a supported hybrid metallocene catalyst prepared by using the method, and a method for preparing a polyolefin using the supported hybrid metallocene catalyst.

Claim (Index 1):
A method for preparing a supported hybrid metallocene catalyst, comprising the steps of\n supporting at least one first metallocene compound represented by the following Chemical Formula 1 or 2 on a support; and supporting a cocatalyst on the support on which the first metallocene compound is supported: in Chemical Formula 1, R 1 , R 2 , R 5 , and R 6  are the same as or different from each other, and are each independently hydrogen or a C1 to C20 alkyl group, R 3 , R 4 , R 7 , and R 8  are the same as or different from each other, and are each independently hydrogen or a C1 to C20 alkyl group, or two or more neighboring groups of R 3 , R 4 , R 7 , and R 8  may be connected with each other to form a substituted or unsubstituted aliphatic or aromatic ring, Q is a Group 4 transition metal, and R 9  and R 10  are pivalate, in Chemical Formula 2, M is a Group 4 transition metal, B is carbon, silicon, or germanium, Q 1  and Q 2  are the same as or different from each other, and are each independently hydrogen, halogen, a C1 to C20 alkyl group, a C2 to C20 alkenyl group, a C6 to C20 aryl group, a C7 to C20 alkylaryl group, a C7 to C20 arylalkyl group, a C1 to C20 alkoxy group, a C2 to C20 alkoxyalkyl group, a C3 to C20 heterocycloalkyl group, or a C5 to C20 heteroaryl group, X 1  and X 2  are pivalate, and C 1  and C 2  are the same as or different from each other, and are each independently represented by one of the following Chemical Formula 3a, Chemical Formula 3b, Chemical Formula 3c, or Chemical Formula 3d, provided that at least one of C 1  and C 2  is represented by Chemical Formula 3a, in Chemical Formulae 3a, 3b, 3c, and 3d, R 1  to R 28  are the same as or different from each other, and are each independently hydrogen, halogen, a C1 to C20 alkyl group, a C2 to C20 alkenyl group, a C1 to C20 alkylsilyl group, a C1 to C20 silylalkyl group, a C1 to C20 alkoxysilyl group, a C1 to C20 ether group, a C1 to C20 silylether group, a C1 to C20 alkoxy group, a C6 to C20 aryl group, a C7 to C20 alkylaryl group, or a C7 to C20 arylalkyl group, R\u2032 1  to R\u2032 3  are the same as or different from each other, and are each independently hydrogen, halogen, a C1 to C20 alkyl group, a C2 to C20 alkenyl group, or a C6 to C20 aryl group, and two or more neighboring groups of R 1  to R 28  may be connected with each other to form a substituted or unsubstituted aliphatic or aromatic ring.
