Abstract:
This invention relates to organoaluminum compounds, organoaluminum activator systems, preferably supported, to polymerization catalyst systems containing these activator systems, and to polymerization processes utilizing the same. In particular, this invention relates to catalyst systems comprising ion-exchange layered silicate, a catalyst compound, an activator and an aluminum compound represented by formula: Al(R′) 3−v (R″) v , wherein each R′, independently, is a C 1 -C 30  hydrocarbyl group; each R″, independently, is a C 4 -C 20  hydrocarbenyl group; and v is from 0.1 to 3.

Claim (Index 12):
The catalyst system of  claim 1 , wherein the catalyst compound is represented by the formula:\n T j L A L B L C i MDE where, M is a group 3, 4, 5, or 6 transition metal atom, or a lanthanide metal atom, or actinide metal atom; L A  is a substituted or unsubstituted monocyclic or polycyclic arenyl pi-bonded to M; L B  is as defined for L A  or is J, a hetero-atom ancillary ligand bonded to M through the heteroatom; the L A  and L B  ligands may be covalently bridged together through a bridging group, T, containing a group 14, 15 or 16 element or boron wherein j is 0 or 1; L C i , is an optional neutral, non-oxidizing ligand having a dative bond to M; i equals 0, 1, 2 or 3; and, D and E are independently mono-anionic labile ligands, each having a sigma-bond to M, optionally bridged to each other or to L A , L B  or L C .
