Patent ID: 6958375

Claim:
A process for forming a 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 1 -C 20 hydrocarbyl; ------ represents a bond between an A atom and a carbon atom, wherein said bond is selected from a single or double bond; and each x independently represents an integer of 0, 1 or 2, provided that when A represents a nitrogen or phosphorous atom and --- represents a double bond then x is 1; when A represent either a nitrogen or phosphorous atom and ---- represents a single bond, then x is 2; when A represents either an oxygen or sulfur atom and ---- represents a double bond, then x is 0; and when A represents either an oxygen or sulfur atom and ---- represents a single bond, then x is 1; and the lines joining each A to each other A represent a C 2 to C 90 hydrocarbon based group; providing as Component II at least one a transition metal compound represented by the formula: M X L 2 L′ a II 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 3 to C 24 hydrocarbon based group, associated through a covalent or dative bond to M, and which, together with M, constitute a ring or fused ring structure; and providing as Component III a support-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 said support-agglomerate further having from 0.1 to 10 weight percent chromium atoms immobilized thereto; or precursor components for said composite selected from (A) at least one inorganic oxide and (B) at least one ion-containing layered component and (C) a chromium compound soluble in an inert liquid in an effective amount to provide 0.1 to 10 weight percent immobilized chromium with respect to the support-agglomerate, said (A) to (B) weight ratio being from 0.25:1 to 99:1; contacting Components I, II and III in the presence of an inert liquid, said contacting being conducted under conditions to cause Components I, II and III to form a coordination catalyst composition.
