dc.description.abstract | 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, ε, of about two times 3η_0 whereas the bidisperse melts have a maximum of up to a factor of seven times the Trouton limit of 3η_0. The Wiest model which incorporates anisotropic drag and finite extensibility may be used to interpret the results in molecular terms. | en |
