Development of a Novel Method for Evaluation of Interfacial Tension between Polymer Melts
A novel method for the evaluation of interfacial tension of high viscosity polymer melts is described. The method involves the tracking of the shape evolution of a highly deformed droplet of one material imbedded in a second one. This makes it possible to determine the interfacial tension over a relatively short time period. The imbedded material is initially either a fiber or a disk. The techniqu
