  • Bimodal polyethylene pipe composition and article made therefrom
    Patent number: 7129296
    Abstract: The 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, MWDL, of less than about 8. In some embodiments, the HMW component is characterized by a reverse comonomer distribution.
    Type: Grant
    Filed: April 2, 2004
    Date of Patent: October 31, 2006
    Assignee: Dow Global Technologies Inc.
