12 Claims

1. A bimodal polyethylene homopolymer composition consisting essentially of a higher molecular weight polyethylene homopolymer component (HMW component) and a lower molecular weight polyethylene homopolymer component (LMW component); wherein the composition has a density from 0.961 to 0.980 gram per cubic centimeter (g/cm³); a melt index (I₂) from 0.2 to 2.0 gram per 10 minutes (g/10 min.); a gel permeation chromatography (GPC) resolved bimodality from Log (M) 4.01 to Log (M) 4.99; an amount of the HMW component from 30 to 70 weight percent (wt %) based on the combined weight of the HMW and LMW components; and a number-average molecular weight (M_n) from 3,000 to 4,990 grams per mole (g/mol).
