Front Cover: In this work, a modeling pathway and software tool for linking entangled linear polymer molecular properties to linear viscoelasticity and melt index (MI) values is presented. A reptation model links molecular properties to the flow curve, and then, an ANSYS Polyflow model calculates MI values based on the flow curve predicted. The method is thoroughly tested and validated for uni-and bi-modal, low- and high-density polyethylene grades. An overall accuracy level in the range of 90% on average is exhibited, considering both model prediction steps: (i) MWD to flow curve and (ii) flow curve to MI. These promising results offer a valuable tool to enhance product development toward the direction of end-use polymer bulk properties prediction. Further details can be found in the article by Vasileios Touloupidis,* Christof Wurnitsch, Alexandra Albunia and Girish Galgali on page 392.
