Abstract: The invention relates to a method for producing compositions containing vinylaromatic copolymers which are obtained in an emulsion polymerization process and comprise production-related salt inclusions. Said compositions are characterized by an improved surface quality once the granulates have been moistened by bringing same in contact with liquid water and have been stored in said water, thus making the compositions suitable for producing molded articles having a class A surface that remains flawless over time.
