The oscillatory shear response of polymers offers a convenient measure of the viscoelasticity of these materials. Coupling well known analytical approaches with one of the many commercial devices available, one may determine polymer structural parameters of scientific and engineering importance. Such dynamic mechanical properties may be used to characterize the temperature and molecular weight dependence of the linear viscoelastic response of rubbery amorphous polymers. Recognition of the importance of these properties in polymer flow behavior clarifies many flow related phenomena.
