System acetonitrile-cyclohexane as immiscible solvents in the presence of polystyrene-polymethylmethacrylate (PS- PMM) block or graft copolymers or also for the system DMF-hexane in the presence of polystyrene-polyisoprene (PS- PI) block or graft copolymers are studied. For such systems only block or graft copolymers give stable oil-in- oil emulsions are observed.
