The invention relates to a metallocene complex according to formula (A): wherein R1 is selected from C1-C10 alkyl, C6-C20 aryl, C7-C20 aralkyl groups, and C1-C10 alkoxy groups, wherein R2 is selected from H, C1-C10 alkyl; wherein R3-R6, R10 are independently selected from H, C1-C10 alkyl, C6-C10 aryl, and wherein R3 and R4, R4 and R5, or R5 and R6 can be connected to form a ringstructure; 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, and wherein each R7 independently is selected from C1-C6 alkyl or aryl groups. The invention also relates to a catalyst comprising the reaction product of the metallocene complex and a cocatalyst. Further the invention relates to a (co)polymerization process of olefinic monomers. 

Dihydrocarbyl-silyl-bridged-1,3 disubstituted-2-indenyl metallocene complexes for olefin polymerization

The invention relates to a metallocene complex according to formula (I), wherein R1 is selected from C2-C10 alkyl, preferably C3-C10 alkyl, C6-C20 aryl, C7-C20 aralkyl groups, wherein R2 is selected from H, C1-C10 alkyl, and wherein R3, R4, R5 and R6 are independently selected from H, C1-C10 alkyl, C6-C20 aryl, or C7-C20 aralkyl groups and wherein R3 and R4, R4 and R5, or R5 and R6 can be connected to form a ring structure wherein M is selected from Ti, Zr and Hf, X is an anionic ligand to M. The invention also relates to a catalyst comprising the reaction product of the metallocene complex and a cocatalyst. Further the invention relates to a (co)polymerization process of olefinic monomers.
