Supported dual transition metal catalyst systems

The present invention (for example, Lac-ethylene-bis (indenyl) zirconium dichloride), metallocene or constrained geometry pre-catalyst transition metal compound with at least one metal, at least one non-metallocene, non-constrained bidentate transition metal compound or tridentate geometry transition metal compound (e.g., tridentate pyridine-2,6-diacetyl-bis (2,4,6-trimethyl Oh put) FeCl2), For the support-activator (such as one or more, spray dried silica / clay the assembly), and, optionally, one or more of the organo metallic compound (e.g., triisobutyl aluminum) containing a controlled amount It relates to coordination catalyst systems, and methods for their preparation. The resulting double-transition metal catalyst system is suitable for the addition polymerization of ethylenically unsaturated monomers in the polymer, and acetylene, for example, a broad molecular weight distribution, Mw / Mn and a polymer having a good polymer morphology.
