METHOD FOR THE PRODUCTION OF ABS COMPOSITIONS HAVING AN IMPROVED SURFACE

摘要

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 extruded polymer, before being granulated, or the granulate, after being granulated, has been moistened by bringing the polymer in contact with liquid water in a water bath, a tube system filled with water, or a dipping tank, thus making the compositions suitable for producing molded articles having a class A surface that remains flawless over time.
