SOLID-STATE SHEAR PULVERIZATION OF POLYMER MIXTURES

摘要

This disclosure describes a composition including an ultra-high molecular weight polymer and a low molecular weight polymer and having a bimodal molecular weight distribution and articles including the composition. This disclosure further describes methods including providing a mixture of an ultra-high molecular weight polymer and a low molecular weight polymer, and applying solid-state shear pulverization to the mixture to form a bimodal molecular weight alloy. This disclosure also describes methods that include providing a mixture including a first polymer and a second polymer, and applying solid-state shear pulverization to the mixture to disperse the first polymer in the second polymer.
