Abstract
The movement of poly (vinyl butyral) (PVB) and dibutyl phthalate (DBP) plastic solution under the influence of capillary forces was observed directly by hot-stage optical microscopy (T=160°C). Migration of a PVB-DBP droplet within a tapered capillary was examined, allowing the surface tension of the binder system at elevated temperatures to be measured, while maintaining constant composition. Calculated surface tension values for PVB-DBP plastic at T=160°C ranged from 8×10 -3 to 20×10 -3 N/m (8 to 20 dyn/cm); the large error was attributable primarily to the difficulty in measuring the radii of curvature of the leading and trailing edges of the droplet.
