ABSTRACT

This chapter describes a dynamic Monte-Carlo method for the simulation of polymer networks in three dimensions with detailed information on the molecular structure of the systems. The networks are analysed concerning network defects, entanglements or the elastically active material and compared with the theory on formation and structure of polymer networks. Since for any dangling structure there is only one path to the network, this criterion is still the basis for the estimation of the elastically active and the viscous part of a polymer network. The simulation method used in the work was developed by Carmesin and Kremer. For the length distribution of rings for both, cross-linked and end-linked networks, It is required two different approaches for description, but only one central point regarding visco-elasticity. The influence of trapped entanglements on the elastically active network structure is twofold. Trapped entanglements can activate a pending ring or they can connect parts of the sol to the network.
