Abstract: Polystyrene foam beads (I) having a diameter of 5-20 mm and a bulk density of 5-20 g/l are prepared by (A) dissolution of 5-25 wt.% polystyrene containing 1-10 wt.% graphite uniformly distributed in styrene, (B) dispersion of the solution in water and addition of propellant, suspension stabilizer and peroxide initiator, (C) polymerization of the styrene, (D) isolation of the propellant containing beads, (E) pre-foaming of the beads with steam.
