Abstract

The water activity and its temperature dependence as a function of the amount of water in the L~2~‐phase of the (water/Aerosol OT/isooctane)‐system (s. Exper. Part) was determined with the help of a differential pressure gauge and a precision cathetometer. A theoretical approach based essentially upon a solution of the Poisson‐Boltzmann equation with appropriate boundary conditions led to a description of the activity plot in excellent agreement with experimental results.

## Abstract Solutions of blockcopolymers (POE‐b‐PI‐b‐POE) in fluids of interacting aqueous nanodroplets (W/O microemulsions) are studied. The interaction strength between the (pseudo) two components is measured by the shift of the percolation temperature relative to that of the pure microemulsion.

The surface area occupied at the air/water interface for cycloalkanols and ␣,-alkanediols has been estimated from surface tension measurements. From these data, standard free energies of transfer of the alkanols from the bulk of the solution to the interface were obtained. Cycloalkanols constitute a

We carried out an investigation on the influence of several alkylamines, frequently present in reactions carried out in microemulsions, on the properties of the water/AOT/isooctane system. The presence of alkylamines has an important effect on the electrical percolation phenomena. This effect of ami
