摘要：

The kinetic rate equation proposed by Mewis and Denn (1983) for their structural network model is found to predict accurately the large amplitude oscillatory shear behavior of molten low density polyethylene IUPAC X. Spectral analysis is used to compare the predictions of several kinetic rate equations. Frequency versus strain amplitude maps are constructed to examine each harmonic of the shear stress response predicted by the Mewis-Denn model. A Pipkin diagram is calculated for this model using contours for the amplitude of the third harmonic.
