WebA warm thank you to the organisers of the "Future of Rheology" seminar series at the Society of Rheology for allowing me to present my graduate research work… WebWhen the clay content was increased, the droplet of the dispersed phase (PP) was shown to elongated structure. The elongated structure could be explained by the decrease of the viscosity ratio of the PP and continuous phase (ABS) with clay, which corresponded to the increase of the viscosity of the continuous phase (ABS/clay).
