ABSTRACT:
Provided is a process for producing a polyolefin having a multimodal molecular weight distribution, which process comprises: (a) polymerizing a first olefin monomer in the presence of an isomerizable metallocene catalyst, to form a first multi-modal polyolefin component; and (b) polymerizing a second olefin monomer in the presence of a second metallocene catalyst to form a second polyolefin component; wherein the molecular weight distribution of the first polyolefin component overlaps with the molecular weight distribution of the second polyolefin component.
