摘要： 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.
