Abstract: A process for producing expandable styrene polymers via polymerization of at least one vinylaromatic monomer in aqueous suspension in the presence of at least one halogenated polymer as flame retardant, graphite, and blowing agent, which comprises the presence, in the aqueous suspension at the start of the polymerization reaction, of from 1 to 30% by weight of at least one styrene polymer, based on the entirety of monomers and styrene polymer, and likewise the presence of at least one halogenated polymer as flame retardant in the styrene polymer used at the start of the polymerization reaction.

Abstract: The present invention relates to a method for producing a molded body by the selective laser sintering of a sinter powder (SP). The sinter powder (SP) contains at least one polyamide (P) and 5 to 50 wt %, preferably 10 to 50 wt %, of at least one aluminum silicate. The at least one aluminum silicate has a D50 value in the range of 2.5 to 4.5 μm. The present invention also relates to molded bodies obtainable by means of the method according to the invention.
