The invention relates to a new catalyst component for the polymerization of olefins comprising a compound of formula CyLMZ, wherein M is a Group 4-6 metal, Z is an anionic ligand, p is the number of anionic ligands, Cy is a mono- or poly-substituted cyclopentadienyl-type ligand and L is a guanidinate ligand of the formula wherein: each A is independently selected from nitrogen or phosphorus 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. The invention also relates to a catalyst system for the polymerization of olefins and a process for the polymerization of at least one olefin having 2 to 20 carbon atoms.

Catalyst component for the polymerization of olefins having a guanidinate 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 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. 

Ti catalyst systems comprising substituted cyclopentadienyl, amidine and diene ligand

The invention relates to a process for the production of an organometallic compound according to formula (1): MALYXR(formula 1) where: M is a metal of groups 3-13 or the lanthanide series, and p is the valency of the metal M, A represents an anionic spectator ligand whose valency v is 1 or 2, Y is a spectator ligand represented by formula (2): wherein the spectator ligand is covalently bonded to the metal M 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 an atom of groups 15-16, through which Subis bonded to the imine carbon atom, suband submight be connected to each other forming a ring system, r is an integer&#x3e;0, L is an optional neutral Lewis basic ligand, j is an integer denoting the number of neutral ligands L, X is an halide, and R is an anionic ligand, wherein an organometallic reagent according to formula (3), MALX(formula 3), is contacted with an alkylating agent, thus forming a precursor in which at least one of the halide atoms is replaced by an anionic ligand R that may be independently selected from the group consisting of alkyl, arylalkyl, aryl, or a combination thereof, which precursor is subsequently contacted with an imine according to formula (2).
