    Abstract: The invention concerns a process for the anionic polymerization or copolymerization of vinyl aromatic compounds such as styrene in solution with an initial monomer concentration of between 40 and 100 wt.% under non-isothermic conditions, preferably in a pipe reactor or pipe assembly reactor, of which a substantial part is provided with means preventing the exchange of heat with the environment, toluene, methylcyclohexane, ethylbenzene or Decalin preferably being used as solvent. The temperature of the polymer solution leaving the reaction chamber is at least 170 DEG C. A styrene polymer containing fewer than 50 ppm monomers is produced.

    Abstract: The invention pertains to a process for continuous preparation of impact-resistant modified vinyl aromatic compounds, in particular impact-resistant modified polystyrene, wherein the vinyl aromatic compound and the impact-resistant modifying agent, a rubber-elastic block copolymer, are produced separately by anionic polymerization in a reaction zone with or without heat exchange with the environment - if necessary with the addition of a solvent - polymerized until complete conversion and the active chain ends are terminated in a per se known way. The invention also pertains to a thermoplastic impact-resistant modified molding compound based on a vinyl aromatic compound with a residual content of less than 50 ppm monomers and less than 100 ppm oligomers.
