Polymer Viscoelasticity and Rheology

The study of polymer viscoelasticity treats the interrelationships among elasticity, flow, and molecular motion. In reality, no liquid exhibits pure Newtonian viscosity, and no solid exhibits pure elastic behavior, although it is convenient to assume so for some simple problems. Rather, all deformation of real bodies includes some elements of both flow and elasticity. Because of the long-chain nature of polymeric materials, their visco-elastic characteristics come to the forefront. This is especially true when the times for molecular relaxation are of the same order of magnitude as an imposed mechanical stress. [Pg.507]

Polymer viscoelasticity and rheology problems are discussed by Alexei E. Likhtman in Chapter 1.06. The emphasis is put on the molecular theory of rheological properties of the systems of entangled macromolecules and on the comparison of this theory with the results of real and computer experiments. [Pg.1]
