摘要： The invention relates to a metallocene complex according to formula A, wherein R1-R10 are independently selected from H, C1-C10 alkyl, C7-C20 Aralkyl groups, and C1-C10 alkoxy groups; wherein R11 is selected from methyl, ethyl, propyl, isopropyl, butyl, phenyl; wherein R1 and R2, R3 and R4, R4 and R5, R5 and R6, R7 and R8, R8 and R9, and/or R9 and R10 can be connected to form a ringstructure; wherein R0 is selected from a C1-C10 alkyl group or an aryl group wherein M is selected from Ti, Zr and Hf, X is an anionic ligand to M, z is the number of X groups and equals the valence of M minus 2. The invention further relates to a catalyst for preparing polyolefins, a process for polymerizing olefins and to polymers prepared by said catalyst system.
