WebAs a model for dense polymer solutions or melts we consider an ensemble of n freely jointed chains consisting of N rigid links in a box. A Lennard‐Jones interaction is taken to model repulsive and attractive interactions between the units of the chains. Dynamics is introduced into the model by allowing for stochastic rotations of the beads of the chains, where the … WebDr. Gary S.

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 … WebGary S. Grest.
