Abstract

An ethylene-based polymer composition has been discovered and is characterized by a Comonomer Distribution Constant greater than about 45. The new ethylene-based polymer compositions are useful for making many articles, especially including films. The polymers are made using a metal complex of a polyvalent aryloxyether.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Nonprovisional Patent Application 12 / 716,004, filed March 2, 2010, the disclosure of which is hereby incorporated by reference for purposes of US practice. Background technique [0003] A variety of polymerized polyethylene polymers exist in recent years, including those prepared using high-pressure free radical chemistry (LDPE), usually more traditional linear low-density polyethylene (LLDPE) prepared using Ziegler-Natta catalysis or geometrically constrained catalysis polyethylene. Some linear polyethylenes, and some substantially linear polyethylenes, contain minor amounts of long chain branching. Although these polymers have various advantages and disadvantages - depending on the application or end use - greater control over the polymer structure is still required. [0004] Applicants have now discovered that post-metallocene catalysts can effectively polymerize ethylene into ...
