    摘要： A polymer composition comprises a low-molecular-weight (LMW) ethylene polymer component and a high-molecular-weight (HMW) ethylene polymer component. Preferably, the LMW polyethylene component and the HMW polyethylene component co-crystallize in the composition such that it exhibits a single or substantially single peak in a lamella thickness distribution (“LTD”) curve. The ethylene polymer for the LMW and the HMW polyethylene components can be either homopolyethylene or ethylene copolymer. Preferably, both components are an ethylene copolymer of the same or different composition (i.e., with the same or different comonomers). A method of making a pipe that includes selecting a polymer composition having a substantially single peak in the LTD curve is described.
