Patent ID: 7141632

Claim:
A process for polymerizing olefin(s) to produce a polymer product, the process comprising contacting ethylene and at least one comonomer with a catalyst system, wherein the catalyst system comprises a poor comonomer incorporating catalyst compound comprising a metallocene structure comprising at least one fused ring cyclopentadienyl ligand bridged to another cyclopentadienyl ligand, where the bridge is a long bridge defined as a bridge containing an Si-O-Si group, and a good comonomer incorporating catalyst compound; wherein the poor incorporator metallocene is a polymerization catalyst which when run under process conditions wherein (Ind) 2 ZrCl 2 would produce a 0.920 g/cm 3 density polyethylene, produces a polymer with a density greater than 0.920 g/cm 3 ; further comprising isolating a polymer product having a density of from 0.910 to 0.940 g/cm 3 , an Mw/Mn value of from 2 to less than 10 and an I 2 value of from 0.1 to 100 dg/min.
