Beschreibung
Zusammenfassung:	LThe invention relates to a polyethylene composition with a bimodal molecular weight distribution and articles made therefrom. The composition comprises a low-molecular-weight (LMW) ethylene homopolymer component and a homogeneous, high-molecular-weight (LMW) ethylene interpolymer component, wherein the LMW component is characterized as having a molecular weight distribution, MWD, of less than about 8. In some embodiments, the HMW component is characterized by a reverse comonomer distribution.
