Abstract: Abstract The viscoelastic responses of some molten polymers, and particularly of low density polyethylene (LDPE), are known to vary with processing history. Reasons for the variations include the effects of shear history on morphological states of the polymer, or on its molecular weight parameters. A typical low density polyethylene has been used to test the shear‐history dependence concept following a variety of processing steps. The polymer was sheared in single‐screw and twin‐screw extruders, and in a high…
