    Abstract: The invention relates to a method for producing graphite particles containing expandable styrene polymers by means of polymerization of styrene in aqueous suspension in the presence of graphite particles and polymerization of two peroxides which disintegrate at varying temperatures. The peroxide which disintegrates at the lower temperature neither forms benzoyl nor benzyl radicals during disintegration.
