Title:
ETHYLENE-BASED POLYMER COMPOSITION FOR FILMS WITH IMPROVED TOUGHNESS
Document Type and Number:
WIPO Patent Application WO/2015/200740
Kind Code:
A3
Abstract:
The invention provides a composition comprising a first composition, comprising at least one ethylene-based polymer, and wherein the first composition comprises a MWCDI value greater than 0.9, and a melt index ratio I10/I2 that meets the following equation: I10/I2 ≥ 7.0 - 1.2 x log (I2). The invention also provides a process to form a composition comprising at least two ethylene-based polymers, said process comprising the following: polymerizing ethylene, and optionally at least one comonomer, in solution, in the presence of a catalyst system comprising a metal-ligand complex of Structure I, as described herein, to form a first ethylene-based polymer; and polymerizing ethylene, and optionally at least one comonomer, in the presence of a catalyst system comprising a Ziegler/Natta catalyst, to form a second ethylene-based polymer.
