Abstract: The invention relates to a transparent, thermoplastic moulding composition containing, based on A + B,… A 5 to 95% by weight of polystyrene and… B 95 to 5% by weight of a non-elastomeric block copolymer with stellate branches, built up from, based on B,… b1 60 to 95% by weight of styrene and… b2 5 to 40% by weight of at least one conjugated diene having 4 or 5 carbon atoms,… prepared in a conventional manner by sequential anionic polymerisation by means of at least one organolithium compound as initiator and in the presence of a solvent, with subsequent coupling, characterised in that component A is produced by conventional anionic polymerisation by means of at least one organolithium compound in the presence of an organic solvent. … The moulding composition is prepared by conventional mixing of components A and B and, if used, C, and is used for the production of mouldings.
