摘要：

A new kinetic orientation model for the description of the rheo-optical behaviour of polymer melts is presented. According to this model, constraints to deformation are introduced by specific changes in Gibbs free energy. The applicability of the model is demonstrated by using it to calculate the transient birefringence in model fluids occurring upon simple elongation with constant stretch rate and constant derivative of the Hencky strain. For both deformation histories, small and large strain rates are considered.
