The present invention provides a borylimide catalyst and further relates to compositions comprising the borylimide catalysts and processes for the polymerisation of olefins (e.g. ethylene) using the borylimide catalysts or the compositions comprising the borylimide catalysts.

Borylimide catalysts

The present invention relates to a new metal complex of the formula (1) 

Metal complex with a bridged cyclopentadienyl amidine ligand

A metal complex of the formula (1)CyAMX(L)&#x2003;&#x2003;(1) 

Metal complex with a lewis base ligand

The invention relates to a catalyst system for the polymerization of olefins comprising a metal complex of formula CyLMD and an activating cocatalyst, wherein M is titanium, Cy is a cyclopentadienyl-type ligand, D is a diene, L is a guanidinate-containing ligand of the formula (I) wherein each A is independently selected from nitrogen or phosphorous and R, R, Rand Rare independently selected from the group consisting of hydrogen, hydrocarbyl, silyl and germyl residues, substituted or not with one or more halogen, amido, phosphido, alkoxy, or aryloxy radicals, and Cy is a mono- or polysubstituted cyclopentadienyl-type ligand, wherein the one or more substituents of Cy are selected from the group consisting of halogen, hydrocarbyl, silyl and germyl residues, optionally substituted with one or more halogen, amido, phosphido, alkoxy, or aryloxy residues. The invention further relates to a process for the preparation of a polymer comprising at least one aliphatic or aromatic hydrocarbyl Colefin wherein the at least one aliphatic or aromatic olefin is contacted with the catalyst system of the present invention. 

Titanium-catalyst system comprising substituted cyclopentadienyl, guanidine and diene ligands

The invention relates to a catalyst system for the polymerization of olefins comprising a metal complex of formula CyLMD and an activating cocatalyst, wherein M is titanium, Cy is a cyclopentadienyl-type ligand, D is a diene, L is an amidinate-containing ligand of formula (1), wherein the amidinate-containing ligand is covalently bonded to the titanium via the imine nitrogen atom, Subis a substituent, which comprises a group 14 atom through which Subis bonded to the imine carbon atom, Subis a substituent, which comprises a nitrogen atom, through which Subis bonded to the imine carbon atom, and Cy is a mono- or polysubstituted cyclopentadienyl-type ligand, wherein the one or more substituents of Cy are selected from the group consisting of halogen, hydrocarbyl, silyl and germyl residues, optionally substituted with one or more halogen, amido, phosphido, alkoxy, or aryloxy residues. The invention further relates to a process for the preparation of a polymer comprising at least one aliphatic or aromatic hydrocarbyl Colefin wherein the at least one aliphatic or aromatic olefin is contacted with the catalyst system of the present invention.
