Interfacial processes selectivity coefficient

The effective compatibilization of binary polymer blends by the addition of a copolymer should reduce the interfacial tension coefficient. Often, it also alters the molecular structure of the interface (as measured by the scattering methods). The process is similar to the emulsification in the classical emulsions. The emulsifier effect on the droplet size follows generally the same behavior as the interfacial tension. This behavior is described by the emulsification curves (evolution of the particle s size with the emulsifier content) and characterizes the additives efficiency. The shape of the emulsifying curve depends greatly on the type of emulsifier and the emulsification process. If the selected compatibilizer is miscible only with one component of the blend, its efficiency...
