Small‐angle neutron scattering was used to study the interactions between AOT/water/decane microemulsions and poly(ethylene oxide)‐polyisoprene‐poly(ethylene oxide) triblocks. The interdroplet spacing seems to be independent of molecular weight and polymer concentration. Scattering experiments on the polyisoprene layer yield a high q exponent of −1.6 ± 0.1, indicating that the layer is swollen by decane.
