“…11 may be used to determine the time-dependent properties of a two-fluid system, but this requires more attention and is not the purpose of the present study. Such analyses have been attempted before (Joseph et al 1992) and reveal the complexity of such two-phase systems. The interface viscoelasticity may also be investigated.…”

“…The spinning drop tensiometry (Vonnegut 1942), its application to polymers (Elmendorp and de Vos 1986;Joseph et al 1992), the pendant drop method (see for example Kamal et al 1997), the filament thread method (Cohen and Carriere 1989), the embedded disk retraction method (Rundqvist et al 1996), the ellipsoidal drop retraction (Luciani et al 1997) or combinations of such methods (filament thread method -ellipsoidal retraction, Tjahjadi et al 1994), all require a very well designed drop or filament to be inserted into another polymer, which is sometimes very difficult. In our instrument, all that is needed is to mix two polymers without having to worry about shaping droplets.…”

“…Moreover, rheological information on the drop and suspending fluids may be deduced from the time-dependent distortion of the drop. Previous studies analyzing the time-dependent features of this problem [5,7] have assumed that since the drop is being stretched, the fluid motion may be analyzed as if the drop has been placed in an extensional flow. Hsu and Flumerfelt [5] indicated that this approximation is only valid for highly distorted drop shapes.…”

“…These methods include the pendant drop method, 4 -6 the sessile drop method, 7 and the spinning drop method. 8,9 These methods require an accurate measurement of the steady-state shape of the liquidliquid interface and the density difference. Because most polymer pairs have high viscosities, low interfacial tension values, and low density differences, the time to an equilibrium is very long, which leads to the thermal degradation of polymer melts and inaccurate interfacial tension value.…”
