Investigation of the mobility of amphiphilic polymer--AOT reverse microemulsion systems using electron spin resonance. 
Amphiphilic polymers can be used as tools to manipulate the behavior of reverse microemulsions.  EPR spectroscopy employing the spin probe 5-doxyl stearic acid was used to study the adsorption of a comb type polymer (polymaleic anhydride octyl vinyl ether) and a diblock polymer (polybutadiene-ethylene oxide) onto reverse microemulsion droplets formed from Aerosol-OT/heptane/water.  The findings indicate that the comb type polymer was adsorbed by the reverse microemulsion drops at low polymer concentrations causing a structural change of the micelle.
