    摘要： A process for the continuous preparation of rubber-modified polymers of vinyl-aromatics, wherein a mixture which contains a monomeric aromatic vinyl compound and from 3 to 30% by weight, based on the monomer, of an elastomeric polymer, with or without a solvent, is polymerized, in the presence of a free radical initiator and in the presence or absence of a mercaptan as chain transfer agent, at from 80.degree. to 180.degree. C., with stirring, in a cascade of two or more isothermally operated reaction zones and of one or more additional reaction zones which can be operated isothermally or with a rising temperature profile in such a way that the residence time of the reactants in the first reaction zone is .ltoreq.35 minutes. The polymer obtained is freed from vinyl-aromatic monomer, and from any solvent, in a devolatilization zone. The product is useful for the production of injection moldings.

    摘要： (Co)polymers which are composed of one or more monomers from the group comprising(a) the vinyl-aromatic monomers and(b) the ethylenically unsaturated monomersand furthermore contain one or more monomer components (a) or (b), or (a) and (b), as unreacted residual monomers are treated at above the glass temperature of the (co)polymer and in the presence of one or more assistants, which have been added to the (co)polymer. The assistant used is a bicyclic compound of the general formula I ##STR1## where X is a methylene, ethylene, 1,1-ethenyl, 1,2-ethenyl, carbonyl, azo, amino, ether or thioether group which is unsubstituted or substituted by halogen, alkyl, alkenyl, cycloalkyl, aryl, carboxyl, carboxyalkyl, an ether group or a thioether group, R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are each hydrogen, halogen, alkyl, alkenyl, cycloalkyl, aryl, carboxyalkyl or nitrile, R.sup.5 and R.sup.6 are each hydrogen, halogen, alkyl or carboxyalkyl, and R.sup.7 and R.sup.8 are each hydrogen, halogen, alkyl, alkenyl, aryl, carboxyalkyl, carboxyl or nitrile.
