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 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.

Abstract: The invention relates to a method for producing compositions containing vinyl-aromatic copolymers that are obtained in an emulsion polymerization process and comprise production-related salt inclusions. Said compositions are characterized by improved surface quality following storage in a warm-humid environment and are therefore suitable for producing molded articles having a class A surface that remains flawless over time.

Abstract: Described herein are polymer compositions comprising at least one inorganic salt comprising a cation selected from the group consisting of alkali metals, alkaline earth metals and aluminum, and an anion selected from the group consisting of chloride, sulfate, nitrate, phosphate, acetate and formate, in a concentration of 100 to 5000 mg/kg, based on the composition, and wherein the salt is present in the composition exclusively in dissolved form or in the form of amorphous and/or crystalline inclusions having a size of not more than 60 ?m. Compositions of the present invention are distinguished by an improved surface after heat-moisture storage and are suitable in particular for the production of moldings with a high gloss finish that demand a class A surface, which have optionally been subjected, in whole or in part, to a further surface treatment step involving e.g. lacquering, in-mold decoration, or metallization by vacuum deposition or galvanization.

Abstract: The invention relates to impact-modified polycarbonate compositions which are distinguished by high heat resistance and good melt flow behaviour. In addition, the mouldings produced from the compositions according to the invention in an injection-moulding process can be metallised, the resulting metallised mouldings having a surface with a particularly high and, in particular, homogeneous gloss. The invention thus also provides the metallised mouldings produced from the compositions according to the invention.
