Abstract:
1. A microemulsion, comprising a surfactant and a cosurfactant, wherein said cosurfactant is a mixture, wherein said mixture comprises a surfactant and a cosurfactant, wherein said cosurfactant is an amphiphilic comb polymer comprising a backbone, wherein at least two side chains are attached to said backbone, and wherein: (i) said at least two side chains differ from one another, (ii) said at least two side chains differ from the backbone in their amphiphilic character, or (iii) said at least two side chains differ from one another and said at least two side chains differ from the backbone in their amphiphilic character, wherein said comb polymer comprises repeat structural units [A] where the structural units [A] form the backbone and the structural unit [A′] has an anchor function for binding the side-chain-forming structural units [X] and wherein the variables n, m and l are mole fractions where n+m+l=1, n≧m and l>m.
