Immiscibility and inter-facial tension between polymer liquids: Dependence of molecular weight
In an effort to extend knowledge of the variation of interfacial tensions with molecular weight, the authors have measured this property for available liquids which are members of several representative homologous systems. These include pairs of fluids from the homologous series of polyisobutylenes, polydimethyl siloxanes, perfluoroalkanes, and n-alkanes. Where possible, the authors also have examined the variation with chain length of the nonaqueous liquid-water interfacial tension, and contact angles of liquid homologs on a nonwettable surface. Since the existence of a finite interfacial tension is a corollary of immiscibility, it is apparent that these effects are closely related to the question of miscibility between the liquid pairs.
