Abstract
In various embodiments, a bimodal polyethylene composition may have a density (ρ) from 0.952 g/cmto 0.957 g/cm, a high load melt index (I) from 1 to 10 dg/min, and a z-average molecular weight (M) from 3,200,000 to 5,000,000 g/mol. The bimodal polyethylene composition may also have a peak molecular weight (M) defined by the equation: M<−2,805.3 MWD+102,688, wherein MWD is a molecular weight distribution defined by the equation: MWD=M/M, Mis a weight average molecular weight of the bimodal polyethylene composition, M) is a number average molecular weight of the bimodal polyethylene composition. Additionally, the bimodal polyethylene composition has a ratio of the (Mz(GPC)) to the Mw(GPC) from 8.5 to 10.5. Articles made from the bimodal polyethylene composition, such as articles made by blow molding processes, are also provided.
