## Abstract Rheological properties of high and low density polyethylene melts (HOPE and LDPE) were measured under two different deformation modes: sinusoidal strain (βdynamicβ) and constant rateβofβstrain (βsteadyβstateβ). For the sinusoidal measurements, a torsional geometry was used, whereas the
## Abstract The rheology of a range of polymer melts has been measured at strain rates above those attained during conventional rheometry using an instrumented injection molding machine. Deviations from shear thinning behavior were observed at high rates, and previously unreported shear thickening
