摘要： Polymer articles and processes of forming the same are described herein. The processes generally include providing a bimodal ethylene based polymer, blending the bimodal ethylene based polymer with a nucleator to form modified polyethylene and forming the modified polyethylene into a polymer article, wherein the polymer article is selected from pipe articles and blown films.
