Primitive Chain Network Simulations for Relaxation Behaviors of Polymeric Materials

Abstract

Prediction of relaxation behavior of polymeric materials from molecular architecture attracts industrial interests and scientific challenges. In this study a coarse-grained molecular model called primitive chain network model is developed. The model is capable for quantitative prediction of linear and non-linear viscoelasticity of entangled polymers. Also it is indicated that the simulation for cross-linked network is fair, though quantitative test is demanded.
