  • Process for Preparing a Polyethylene Resin in a Double Loop Reactor with a Mixture of Bis-indenyl and Bis-tetrahydroindenyl
    Publication number: 20110015353
    Abstract: The present invention discloses a process for preparing polyethylene resins in a double loop reactor wherein the catalyst system comprises a bis-tetrahydroindenyl and a bis-indenyl catalyst component deposited on the same support. It also discloses the polyethylene resins obtained by the process and their use to prepare films having a good compromise of haze, processing and mechanical properties.
