Ethylene polymers and copolymers with high optical opacity |
摘要 |
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.
