Abstract:
This invention relates to a supported catalyst system and process for use thereof. In particular, the catalyst system includes bridged hafnium metallocene compound, an unbridged metallocene compound, a support material and an activator. The catalyst system may be used for preparing polyolefins.

Claim (Index 23):
A process to produce linear low density polyethylene comprising contacting one or more monomers with a supported catalyst system of  claim 1  wherein:\n 1) when the two catalysts (A) and (B) and activator are supported on the same support and run under the polymerization conditions, an ethylene polymer is produced having: a) an RCI,m greater than 30 and an Mw/Mn of greater than 3 and less than 5; or b) an RCI,m greater than 50 and an Mw/Mn of greater than 5; \n 2) when the supported bridged group 4 metallocene catalyst compound (A) is run under the same polymerization conditions of step 1) except that the unbridged metallocene catalyst compound (B) is absent, an ethylene polymer is produced having an RCI,m greater than 20; and \n 3) when the supported unbridged metallocene catalyst compound (B) is run under the same polymerization conditions of step 1) except that the bridged group 4 metallocene catalyst compound (A) is absent, an ethylene polymer is produced having a negative RCI,m.
