## Abstract Rheological properties of high and low density polyethylene melts (HOPE and LDPE) were measured under two different deformation modes: sinusoidal strain (β€œdynamic”) and constant rate‐of‐strain (β€œsteady‐state”). For the sinusoidal measurements, a torsional geometry was used, whereas the
