Basic Rheology of Polymer Melts. An Introductory Polymer Science Experiment

Abstract
A basic experiment is proposed to illustrate the rheological behavior of polymer melts. Viscoelastic properties are studied by means of dynamic mechanical testing. Time dependence and time-temperature correspondence are explored by building an experimental "master curve". Effects of molecular parameters such as molecular weight and molecular weight distribution are discussed for all viscoelastic quantities. Attention is focused on the rubbery plateau modulus, the Newtonian viscosity, and the cross-over point between the elastic and the viscous moduli.
