This paper reports on studies of the phase behavior of systems of the type H2O-oil-amphiphilue-electrolyte with a simple polar polymer as nonionic amphiphile. It turns out that the system behaves similar to systems with monomeric nonionic amphiphiles which is due to the fact that both the binary system H2O-polar polymer and oil-polar polymer show the same characteristic features as the corresponding systems with monomeric amphiphiles. The results suggest the tailoring of polydetergents by varying both their amphiphilicity and their degree of polymerization in order to obtain highly efficient amphiphiles for the preparation of socalled microemulsions.
