Abstract:
1. A coordinating catalyst system capable of polymerizing olefins comprising: (I) a pre-catalyst comprising at least one non-metallocene, non-constrained geometry compound selected from bidentate ligand containing transition metal compound, tridentate ligand containing transition metal compound and mixtures thereof, wherein the transition metal is at least one member selected from Groups 3 to 10 of the Periodic table; in intimate contact with (II) chromium immobilized support-agglomerate comprising a composite of (A) at least one inorganic oxide component; and (B) at least one ion containing layered material; chromium atoms immobilized to component (A), Component (B) or both; wherein the amount of the pre-catalyst (I) and support-agglomerate (II) provides a ratio of micromoles of pre-catalyst to grams of support-agglomerate of from about 5:1 to about 500:1.
