In this model, the single chain diffusion is represented by Brownian motion of beads connected by … Webb31 aug. 1998 · We present an extensive molecular‐dynamics simulation for a bead spring model of a melt of linear polymers. The number of monomers N covers the range from N=5 to N=400. Since the entanglement length N e is found to be approximately 35, our chains cover the crossover from the nonentangled to the entangled regime. The Rouse model …
