Elongational Viscosity of Monodisperse and Bidisperse Polystyrene Melts
The startup and steady uniaxial elongational viscosity have been measured for two monodisperse polystyrene melts with molecular weights of 52 kg/mole and 103 kg/mole, and for three bidisperse polystyrene melts. The monodisperse melts show a maximum in the steady elongational viscosity vs. the elongational rate, ǫ̇, of about two times 3η0 whereas the bidisperse melts have a maximum of up to a fac...
متن کاملPressure Dependence of Viscosity of Glassforming Melts
We suggest a model in which viscosity η is related to entropy of the system. The model successfully describes the dependence of viscosity on pressure. A master equation is developed that allows a comparison of data obtained at different temperatures. Earlier, in the framework of the same model we described the dependence of viscosity on temperature. The present treatment gives a simple interpre...
متن کاملViscosity of high crystal content melts: dependence on solid fraction
The rheological properties of suspensions containing high solid fractions are investigated. Attention is focused on viscosity of sil-icate and magmatic melt systems. A general empirical equation which describes the relative viscosity of suspensions as a function of suspended solid fraction is proposed. In the limit of very dilute solid concentrations it reduces to the Einstein equation. The pro...
متن کاملViscosity and density measurement methods for polymer melts
In this article review of density and viscosity measurement methods is presented, including ultrasonic pulse echo methods, which are capable to measure these properties of polymer melts. The methods are presented according to measurement principles, methodology, accuracy and possibility to measure density and viscosity of polymer melts on-line during extrusion process. Such measurements are ver...
متن کاملNonlocal viscosity of polymer melts approaching their glassy state.
The nonlocal viscosity kernels of polymer melts have been determined by means of equilibrium molecular dynamics upon cooling toward the glass transition. Previous results for the temperature dependence of the self-diffusion coefficient and the value of the glass transition temperature are confirmed. We find that it is essential to include the attractive part of the interatomic potential in orde...
