Abstract A volume-reducing agent in the form of liquid for preparing foam polystyrene is prepared from the first plasticizer (65-97 wt.%) whose solubility parameter is less than that of polystyrene and the second plasticizer (3-35 wt.%) whose solubility parameter is greater than that of polystyrene through mixing. The method and equipment for using it to prepare foam polystyrene are also disclosed.
