Flameproof, thermoplastic molding compositions based on styrofoam polymers which contain an organic heterocyclic bromine compound with the grouping N = C-CBr as a flame retardant, and, if appropriate, a blowing agent. The styrene polymers are prepared by polymerizing styrene in aqueous suspension in the presence of the bromine compound, an organic azo compound having a half-life at 70 ° C. of between 2 and 60 min as the polymerization initiator. is used. The molding compounds can be processed into moldings, profiles or foams. |
