MULTIMODAL POLYETHYLENE COMPOSITIONS AND PIPES PRODUCED FROM THE SAME MULTIMODAL POLYETHYLENE COMPOSITION. A multimodal polyethylene composition having at least two polyethylene components, whereby each component has a molecular weight distribution equal to or less than about 5, one component has a molecular weight greater than the other component, and the component of Higher molecular weight has a parameter value "a" equal to or greater than about 0.35 when adjusted to the Carreau-Yasuda equation with n = 0. |
