## Abstract In order to understand the viscoelastic non‐linearities in polyethylene, dynamic ultrasonic properties of high density polyethylene (HDPE), linear low density polyethylene (LLDPE) and their blends were studied. In the case of HDPE and HDPE‐rich films, for which the nonlinearity is high,

## Abstract Viscoelastic nonlinearity was examined on uniaxially drawn films of high density and linear low density polyethylenes and their blends using dynamic ultrasonic measurements. It was found that nonlinearity due to plastic deformations, such as slippage and dislocations, occurs in the fibr
