## Abstract An earlier model relating the variation of the steady‐shear melt viscosity of high‐density polyethylene to the molecular weight distribution is applied toward predicting the steady‐shear elastic compliance, the first normal stress difference, and relaxation spectrum as a function of she
The effect of different thermal treatments on the elastic modulus of high-density polyethylene has been studied in order to determine which of the parameters defining the polymer morphology has the major effect on the modulus. After examination of the effects of crystallinity, spherulite size, and l
