Abstract: The present invention relates to a process for producing expandable styrene polymers containing graphite particles, which process comprises polymerizing styrene, optionally together with 20 percent by weight of comonomers, based on the weight of polymers, in aqueous suspension in the presence of graphite particles having a mean particle size of from 1 to 50 microns with addition of peroxide initiators and adding a blowing agent before, during or after the polymerization. Claimer are also particulate expandable styrene polymers containing graphite particles having a mean particle size of from 1 to 50 microns, wherein the graphite particles are homogeneously distributed in the styrene polymer and the styrene polymer is in the form of round beads having a mean diameter in the range from 0.2 to 2 mm. The invented expandable styrene polymers are used in the production of foam materials having density of about 5 to 35 g/l.
