摘要: The invention relates to a polyethylene composition with a bimodal molecular weight distribution, methods for making the same, and articles made therefrom, such as high topload blow moldings and transmission and distribution pipes. The composition comprises a low-molecular-weight (LMW) ethylene homopolymer component and a homogeneous, high-molecular-weight (HMW) ethylene interpolymer component, wherein the LMW component is characterized as having a molecular weight distribution, MWDL, of less than about 8. In some embodiments, the HMW component is characterized by a reverse comonomer distribution.
