A multiscale simulation method is used to calculate the rheological properties of entangled Nylon 6 melts, including stress relaxation modulus, storage and loss moduli, melt viscosity. The three-level approach includes all-atom, coarse-grained slip-spring models, each operating at different levels resolution encompassing a wide range length scales over nine orders magnitude in time. These model...
