A New Model for Polymer Melts and Concentrated Solutions
A simple mesoscopic model for polymer chains in melts and concentrated solutions at equilibrium is presented. The chain is modeled as a freely jointed bead-rod Kramers chain that makes jumps of the Orwoll-Stockmayer type. The elemental jumps are postulated to have a fractal waiting time distribution. The kinematics of the chain is investigated by a continuous time simulation in which the diffusion properties and the autocorrelation function for the end-to-end vector of the chain are followed.
