Abstract: Process for the preparation of styrenic polymers having an improved color stability by anionic polymerization wherein the obtained terminated polymer solution is fed to a dispersing device to which water is added, fed to a buffer vessel and then is impregnated in a static mixer by addition of further water, carbon dioxide and one or more stabilizers.
