Abstract

Interfacial tension between molten polymers is a key factor that helps predicting the morphology of polymer blends. In this work, the theories of Tomotika and Tjahjadi et al. to measure interfacial tension between molten polymers using the breaking thread method are evaluated and compared. In particular, both theories were tested for PP/PS polymer pair at temperature of 200 °C. The average values of interfacial tension calculated using Tomotika´s theory and Tjahjadi et al.´s theory are 5.88 mN/m and 5.66 mN/m, respectively. (AU)
