Zusammenfassung:Particulate expandable styrene polymers which contain an organic bromine compound as the flameproofing agent and an organic compound possessing a labile C-C, O-O or N=N bond as the synergistic agent for flameproofing. The flameproofing agent is applied to the surface of the particles while the synergistic agent is homogeneously incorporated into the particles. The polymers can be converted to self-extinguishing foams.
