Abstract:

An empirical equation for stress relaxation in the rubbery-flow region was applied to broad- and narrow-distribution polystyrenes. It is shown that over the range of polydispersity and molecular weights tested, the shear viscosity eta state near compliance Je, and the rubbery-flow stress relaxation may be predicted if Mn and Mw are known.
