title = "Characterization of the rheological behavior of thermotropic liquid crystal polymers related to extrusion processes",
abstract = "In this paper, a new rheological model describing the viscosity of thermotropic liquid crystal polymers is developed. The rheological behavior of thermotropic LCP was studied using a high-pressure capillary rheometer, which was equipped with a slit die. The detailed analysis of all experimental investigations showed that the flow behavior cannot be described well with existing models. The new model combines the Bird-Carreau-Yasuda model with a specific yield stress parameter. The temperature dependence of this yield stress is considered like that of the zero-shear-rate viscosity of the Bird-Carreau-Yasuda approach. The new model does not only describe the determined data better than existing models, but it can also describe the three-region flow behavior observed by other authors excellently.",
