Abstract:
A process for polymerizing olefin(s) in the presence of a catalyst system comprising a Group 15 containing bidentate or tridentate ligated metal catalyst compound and a Lewis acid aluminum containing activator, wherein the Group 15 containing metal compound is represented by the formulae: ##STR4##wherein M is metal;each X is a 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 or 16 element;L' is a Group 15 or 16 element or Group 14 containing group;Y is a Group 15 element;Z is a Group 15 element;R.sup.1 and R.sup.2 are independently a C.sub.1 to C.sub.20 hydrocarbon group, a heteroatom containing group having up to twenty carbon atoms, silicon, germanium, tin, lead, or phosphorus;R.sup.3 is absent, a hydrocarbon group, hydrogen, a halogen, or a heteroatom containing group;R.sup.4 and R.sup.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.sup.1 and R.sup.2 may be interconnected to each other, and/or R.sup.4 and R.sup.5 may be interconnected to each other;R.sup.6 and R.sup.7 are independently absent, hydrogen, an alkyl group, halogen, heteroatom or a hydrocarbyl group; andR* is absent, hydrogen, a Group 14 atom containing group, a halogen, or a heteroatom containing group; andwherein the Lewis acid aluminum containing activator is represented by the formula:R.sub.n Al(ArHal).sub.3-n,wherein R is a monoanionic ligand;ArHal is a halogenated C.sub.6 aromatic or higher carbon number polycyclic aromatic hydrocarbon or aromatic ring assembly in which two or more rings or fused ring systems are joined directly to one another or together; andn=1 to 2.
