Liquid state of polymers has unique mechanical properties called viscoelasticity: though it is a viscous liquid, it shows rubber-like elasticity for fast flows. Here I will discuss a few basics for the viscoelasticity of polymeric liquids, how to characterize it for small deformation, how to model it for large deformation, and how to understand it from molecular point of view.
