Abstract

Described herein are polymer compositions comprising 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.
