-25- ABSTRACT OF THE DISCLOSURE The invention relates to objects made of a mixture comprising 70 to 99.9 parts by weight of a polymerizate A, containing 20 to 100% by weight of styrene units with 0.1 to 30 parts by weight of a flame retardant B, which is compatible with A, as the core material, which is provided with a coating of a poly(meth)acrylate C, which is compatible with the mixture made of A and B and which contains 10 to 100% by weight of monomers of the formula I Image where R1 stands for hydrogen or methyl and R2 stands for an optionally alkyl-substituted cycloalkyl group having 5 to 8 carbon atoms or for a non-aromatic, ring carbon containing heterocycle having 4 to 12 rings atoms and at least 2 heteroatoms X = O. S, NH, where the heteroatoms may not stand next to each other, wherein the polymerizate A exhibits less than 10% by weight of polar monomers selected from the group (meth)acrylonitrile, maleic acid anhydride and maleic acid imides.
