Computer simulations of complex polymer systems

A short review is given on computer simulations for two and three dimensional polymer melts. For d = 2 a recently developed Monte Carlo method is used. The chains segregate and the dynamics can be interpreted as Rouse like. For d = 3 the chains strongly interpenetrate each other. The local dynamics follows the reptation model. By mapping the model chains onto chemical species, distances and times are predicted for the onset of reptation for a variety of different systems. © 1990 IOP Publishing Ltd.
