Abstract
A bimodal polyethylene composition that includes ethylene-derived units, and, optionally, one or more other olefin-derived units, wherein the bimodal polyethylene composition possesses a density of at least 0.940 g/cc, an average molecular weight (Mw) of from 200,000 to 370,000, a z-average molecular weight (Mz) of from 1,500,000 to 3,400,000 Daltons, and a z+1 average molecular weight (Mz+1) of from 2,500,000 to 6,800,000 Daltons, is provided in various embodiments. Articles made therefrom and methods of making the same are also provided.
