摘要： A blowing agent is infiltrated into polystyrene resin particles dispersed in an aqueous suspension. Before or during infiltration, a flame retardant solution obtained by dissolving 33-1,000 parts by weight of a powdery flame retardant and 20-200 parts by weight of a flame retardant aid having a 1-hour half-life temperature of 100-250° C. in 100 parts by weight of a plasticizer is supplied to the aqueous suspension to infiltrate the flame retardant and the flame retardant aid into the particles, producing expandable polystyrene resin particles. By dissolving the flame retardant, which doesn't accumulate in the living body and has satisfactory handleability, in a plasticizer, the flame retardant can be evenly infiltrated into resin particles. Consequently, expansion of the expandable particles doesn't result in unevenness of cell density and the particles have excellent heat-fusibility to one another during molding, and molded foam having excellent flame retardancy and heat resistance can be obtained.
