Amphiphilic arborescent block copolymers generate different structures in selective solvents as revealed in computer simulations. The macromolecules do not aggregate in the solution and form monomolecular micelles. Both single- and multicore micelles can be stable.
Adsorption of such macromolecules on liquid (oil−water) interface leads to their flattening and segregation of the blocks: hydrophilic and hydrophobic blocks are exposed toward water and oil, respectively. Even in a dense monolayer, the macromolecules do not interpenetrate, resembling leaves of water lilies. Pretty fast adsorption kinetics of the macromolecules makes them efficient stabilizers of emulsions.
