Abstract

Some recent attempts to investigate the dynamic properties of dilute polymer solutions and polymer melts by molecular dynamics simulations are reviewed. For dilute solutions the dynamics is very well described by the classical Zimm model. For melts we find that the data agree very well with the reptation model. Since only highly idealized models can be treated so far, the models have to be mapped onto the different chemical species. Doing this allows to predict the times and lengths for the onset of reptation for various systems.
