Chapter 5 Rheology of molten polymers

This chapter focuses on the rheology of molten polymers. A central concept in rheology is that force applied to materials results in deformations for solids or flow for fluids. The relative deformation is called strain and the applied force per unit area is called stress. The main objective of rheology is measurement, examination, and development of relations between stresses and the corresponding strains and the change of strains per unit time …
