Abstract: The present invention relates to compounds according to formula I, wherein: R1 is a cyclopentadienyl moiety or a moiety comprising a cyclopentadienyl ring structure; R2 is a moiety M(R5)2 or MR5, wherein M is a metal selected from hafnium, titanium or zirconium, and R5 is F, Cl, I, Br or an alkyl-moiety comprising 1 to 10 carbon atoms, preferably methyl, benzyl, butadiene or pentadiene; R3 is H, an alkyl or aryl moiety comprising 1 to 10 carbon atoms, or a moiety comprising N or O and 1 to 15 carbon atoms; R4 is H, an alkyl or aryl moiety comprising 1 to 10 carbon atoms, or a moiety comprising N or O and 1 to 15 carbon atoms, or a halogen; wherein if R3 is H, R4 is a moiety other than H, and if R4 is H, R3 is a moiety other than H; each R6 is individually selected from H, a halogen, an alkyl moiety, an aryl moiety, a halogen-substituted alkyl moiety, a halogen-substitute d aryl moiety, an alkoxy moiety, a siloxy-moiety, or a nitrogen-containing moiety, preferably H. Such compounds may be used in a catalyst system for olefin polymerisation, particularly ethylene copolymerisation, providing at least one of a high catalyst activity, a high comonomer incorporation, and/or a high molecular weight polymer.

Abstract: The present invention provides a compound according to formula (I): (I) wherein: R2 is a bridging 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.
