    摘要： Toughened vinyl aromatic compounds, in particular high impact polystyrene, are prepared by a continuous process in which the vinyl aromatic compound and the impact modifier, an elastomeric block copolymer, are each prepared separately in a reaction zone by anionic polymerization, with or without heat exchange with the environment and, if required, with the addition of a solvent, and are polymerized until complete conversion is achieved, and the living chain ends are terminated in a manner known per se, and a thermoplastic, toughened molding material is based on a vinyl aromatic compound having a residual content of less than 50 ppm of monomers and less than 100 ppm of oligomers.
