Patent ID: RE41785

Claim:
A process for polymerizing olefin(s) comprising combining said olefin( s ) in the presence of a catalyst system comprising a Group 15 containing bidentate or tridentate ligated metal catalyst compound, wherein the process is conducted at a temperature from between 50° C. to 200° C., and wherein the catalyst compound is represented by the formulae formula : wherein M is metal; each X is an aryl substituted alkyl leaving group; y is 0 or 1; n is the oxidation state of M; m is the formal charge of Y, Z and L or of Y, Z, and L′ ; L is a Group 15 element; L′ is a Group 15 element or Group 14 containing group; Y is a Group 15 element; Z is a Group 15 element; R 1 and R 2 are independently a C 1 to C 20 hydrocarbon group, a heteroatom containing group having up to twenty carbon atoms, silicon, germanium, tin, lead, or phosphorus linear, branched, or cyclic C 2 - C 20 alkyl group ; R 3 is absent, a hydrocarbon group, hydrogen, a halogen, or a heteroatom containing group; R 4 and R 5 are independently an alkyl group, an aryl group, a substituted aryl group, a cyclic alkyl group, a substituted cyclic alkyl group, a cyclic arylalkyl group, a substituted cyclic arylalkyl group or a multiple ring system; R 1 and R 2 may be interconnected to each other, and/or R 4 and R 5 may be interconnected to each other; and R 6 and R 7 are independently absent, hydrogen, an alkyl group, halogen, heteroatom or a hydrocarbyl group; and R* is absent, hydrogen, a Group 14 atom containing group, a halogen, or a heteroatom containing group wherein said Group 15 containing tridentate ligated metal catalyst compound is added to a polymerization reactor in one of a slurry, a solution, an emulsion, a dispersion or a suspension, and wherein said Group 15 containing tridentate ligated metal catalyst compound has an activity of at least 641 g polyethylene/mmol catalyst·atm·h .
