ABSTRACT:
Prefoamed synthetic resin particles are produced by dispersing foamable resin particles in a dispersing medium within a closed vessel, said foamable resin particles containing a water-soluble inorganic substance and a blowing agent therein, and then releasing the foamable resin particles and the medium into an atmosphere of a pressure lower than that inside the vessel, whereby the thus-released foamable resin particles are allowed to undergo foaming.
