Abstract
The tensile properties have been evaluated for high‐density solid‐state polyethylene extruded to different extrusion (draw) ratios. The results are compared with measured and theoretical values on this and other polymers. An extrusion (draw) ratio and a deformation gradient are defined and discussed. The content of extended tie molecules in extruded high‐density polyethylene was calculated from a model and modulus data.Keywords
