Abstract (en)
[origin: WO2013092322A2] The invention relates to a method for producing expandable styrene polymers by polymerizing at least one vinyl aromatic monomer in an aqueous suspension in the presence of at least one halogenated polymer as a flame retardant, graphite, and blowing agent, characterized in that, at the start of the polymerization, the aqueous suspension contains 1 to 30 wt% of at least one styrene polymer with respect to the sum of monomers and styrene polymer and the styrene polymer used at the start of the polymerization likewise contains at least one halogenated polymer as a flame retardant.
