Abstract

The present invention relates to a process for the preparation of compositions comprising vinyl aromatic copolymers prepared by the emulsion polymerisation process and having salt inclusions resulting from their preparation, which compositions are distinguished by an improved surface quality after storage under warm moist conditions and in that respect are suitable for the production of molded bodies having a class A surface.
