## Abstract In order to understand the viscoelastic nonβlinearities 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 HDPEβrich films, for which the nonlinearity is high,
Linear low-density polyethylene (LLDPE) fibers, obtained from the meltflow rate (g/10 min) of 45 and 50, which were polymerized by a metallocene catalyst and a Ziegler-Natta catalyst, respectively, were produced by a high-speed melt-spinning method in the range of take-up velocity from 1 to 6 km/min
## 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
