The stability of W/O emulsion styrene / sorbitan monooleate / water with sorbitan monooleate concentration from 0.2 to 6.3 vol%. was investigated. It was established that emulsions with a surfactant concentration less than 0.4 vol.% are unstable towards sedimentation and coalescence, and ones with surfactant concentration above 2.5 vol.% are unstable towards sedimentation only. Highly porous polystyrene was obtained from stable W/O emulsions. Surfactant concentration in W/O emulsion that is optimal for preparation of highly porous polystyrene was 0.4-0.8 vol.%. If the concentration of surfactant is above 0.8 vol.% the structure of highly porous polystyrene was partially damaged.
