This invention relates to the field of metal-catalyzed olefin
polymerization methods and the polymers and films prepared therefrom. In
one aspect, this invention provides polyethylene and
ethylene/.alpha.-olefin copolymers formed in the presence of
tightly-bridged metallocene catalyst, organoaluminum cocatalyst, and a
chemically-treated solid oxide, and optionally in the presence of
additional cocatalysts. The resins and films prepared from these polymers
exhibit high haze values, low clarity values, and a low coefficient of
friction.
