Filed:

Mar 10, 2004

Appl. No.:

10/797673

Inventors:

Ashish Sukhadia - Bartlesville OK, US
Jerry Stark - Bartlesville OK, US
Max McDaniel - Bartlesville OK, US
Elizabeth Benham - Spring TX, US
Michael Jensen - Bartlesville OK, US
Joel Martin - Bartlesville OK, US
Rajendra Krishnaswamy - Bartlesville OK, US

International Classification:

C08F004/44

US Classification:

526160000, 526943000

Abstract:

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/α-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.
