Abstract: The present invention provides a compound according to formula (I): (I) wherein: •R2 is abridging moiety containing at least one sp2 hybridised carbon atom; •each R4, R4′, R7 and R7′ are hydrogen or moieties comprising 1-10 carbon atoms, wherein each R4, R4′, R7 and R7′ are the same; •each R5, R5′, R6 and R6′ are moieties comprising 1-10 carbon atoms, wherein each R5, R5′, R6 and R6′ are the same; and •Z is a moiety selected from ZrX2, HfX2, or TiX2, wherein X is selected from the group of halogens, alkyls, aryls and aralkyls. Such compound allows for the preparation of catalyst systems that provide improved olefin reactivity, such as ethylene reactivity, increased molecular weight in olefin polymerisation, such as increased Mw in ethylene polymerisation, and increased comonomer incorporation in copolymerisation reactions of olefins, such as in copolymerisation reactions of ethylene with 1-hexene.

Abstract: The invention relates to a metallocene complex according to formula I or II wherein M is a metal selected from lanthanides or transition metals from group 3, 4, 5 or 6 of the Periodic System of the Elements, Q is an anionic ligand to M, k is the number of Q groups and equals the valence of M minus 2, R is a divalent bridging group, R1, R2, R3 and R4 are each independently chosen from the group consisting of hydrogen (H); a halogen atom; a silyl, alkyl, cycloalkyl, aryl, alkylaryl or arylalkyl group; and R5, R6, R7 and R8 are each independently chosen from the group consisting of hydrogen (H); a halogen atom; a silyl, alkyl, cycloalkyl, aryl, alkylaryl or arylalkyl group; or two adjacent radicals R5 and R6, R6 and R7, and R7 and Ware connected with each other in a hydrocarbon ring system. The invention also relates to a catalyst comprising the metallocene complex, to a process for making polyolefms and to the use of the polyolefins for making articles.
