Title: Scaling of activation energy for macroscopic flow in poly(ethylene glycol) solutions: Entangled - Non-entangled crossover
Abstract: We postulate an empirical scaling equation, which accurately describes of polymer solutions, complimenting the paradigm of viscosity. We investigated poly( ethylene glycol) solutions and observed an exponential dependence of viscosity on hydrodynamic radius of a single coil R-h divided by the correlation xi. Properties of the system changed abruptly with the onset of
