Abstract:
1. A process for forming an activated coordination catalyst system useful for the polymerization of olefins comprising: providing Component I selected from at least one ligand forming compound or, precursor compounds for forming at least one ligand forming compound, wherein said at least one ligand forming compound is represented by at least one of the following formulas IA or IB: wherein in each of formulas IA and IB above: each A independently represents an atom of oxygen, sulfur, phosphorous or nitrogen; each R independently represents hydrogen, an unsubstituted or substituted C each x independently represents an integer of 0, 1 or 2, provided that when A represents either a nitrogen or phosphorous atom and the lines joining each A to each other A represent a C providing as Component II at least one a transition metal compound represented by the formula: wherein a is an integer of 0, 1 or 2 such that the sum of a plus 2 equals x, M represents at least one of Group 3 to 10 transition metals of the Periodic Table; and each L and L′, independently represents a member selected from hydrogen, halogen, and hydrocarbon based group associated through a covalent bond to M, or together represent a C providing as Component III a support-activator agglomerate composite comprising agglomerates of at least two components comprising (A) at least one inorganic oxide component and (B) at least one ion-containing layered component; and contacting Components I, II and III in the presence of an inert liquid, said contacting being conducted under conditions sufficient to have Components I, II and III form an activated coordination catalyst composition.
