Primitive chain network model parameters for common polymers

This study reports the unit molecular weight and unit time of the primitive chain network model for eight common thermoplastics: polyethylene, isotactic polypropylene, poly(ethylene terephthalate), polycarbonate, polyamide 6, polyisoprene, polybutadiene, and polystyrene. The parameters were obtained by mapping the model predictions to literature data for the plateau modulus and zero-shear viscosity. Owing to the conversion rules established earlier, the parameters are also expressed in the units used in the multi-chain slip-spring and Kremer-Grest bead-spring models. The latter results are compared with those of earlier studies.
