Abstract
The present invention is directed to a novel one-step method for forming a supported catalyst complex of high activity by substantially simultaneously contacting a bidentate or tridentate ligand forming compound, a transition metal compound and a Lewis acid support-activator agglomerate. The catalyst can be formed prior to polymerization of olefins or within the polymerization reaction zone.
Claims67
A process for forming a coordination catalyst system useful for the polymerization of olefins comprising:
- providing as Component I is selected from at least one ligand forming compound or precursor compounds capable of 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:
- 6
- 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 C1-C20 hydrocarbyl;
- each x independently represents an integer of 0, 1 or 2, provided that when A represents a nitrogen or phosphorous atom x is 1 when said atom A is bonded by a double bond (when represents a double bond) and x is 2 when said atom A is bonded by a single bond (when represents a single bond) and provided that when A represents either an oxygen or sulfur atom x is 0 when said atom A is bonded by a double bond;
- and x is 1 when said atom A is bonded by a single bond;
- and
- the lines joining each A to each other A represent a C2 to C90 hydrocarbon based group;
- providing as Component II at least one a transition metal compound represented by the formula:
- MxL2L′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 C3 to C24 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-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 catalyst composition.
