Theoretical Estimation of Interfacial Tension between Molten Polymers

[摘要] A simple method to calculate the interfacial tension between two immiscible molten polymers has been developed. The theory is based on the significant structure theory of liquids. The energy of adhesion is expressed as a geometric mean of the cohesion energies multiplied by correction factor (¥Õ12), ¥Ä¥Å12=¥Õ12¡î(¥Ä¥Å11¥Ä¥Å22). In the calculation of ¥Ä¥Å11 and ¥Ä¥Å22, a quasilattice of polymer chains has been assumed. It is assured that, besides the dispersion force, the polar force interactions between polymer constituent groups should be considered in the calculation of the interfacial tensions.
