Scale-Dependent Viscosity in Polymer Fluids.
In this communication, we use simple physical arguments to construct a "phase diagram" of various frequency and wave vector-dependent regimes of effective viscosity for polymer fluids, including nonentangled and entangled melts, semidilute solutions without and with hydrodynamic interactions, as well as the more exotic case of a melt of unconcatenated ring polymers.
