Notes:
Many attempts to correlate steady-state and dynamic rheological data have been reported. Thus far, the correlations have not been convincing, particularly for polymer melts that exhibit highly non-Newtonian behavior. The purpose of this work was to provide a means for obtaining a useful correlation. The Maxwell viscoelastic model was used to correlate data from four different modes of shear - two involving steady-state deformation and two involving dynamic deformation. As certain defined requirements were met, excellent agreement was obtained for polymer melts that represent a wide range of viscoelastic behavior. One of these requirements was that the polymer molécule should have a certain degree of flexibility.
