Abstract:
1. A process for preparing a polyolefin comprising: including as components in a polymerization mixture a metallocene catalyst supported on MAO/silica, wherein the catalyst selected from the group consisting of a CpFlu catalyst, a bis-indenyl catalyst, bridged mono-ligand metallocene compounds, and a combination thereof, and a polymerization diluent; selecting a cocatalyst selected from the group consisting of tri-n-octylaluminum (TNOAl), partially hydrolyzed tri-n-octylaluminum (TNOAl), tri-n-hexylaluminum (TNHAl), and combinations thereof; precontacting the metallocene catalyst and cocatalyst; and contacting at least one monomer under polymerization conditions with the polymerization mixture to produce a polyolefin.
