Abstract: Process for the preparation of very low haze and color stable styrenic polymers by anionic polymerization wherein the obtained terminated polymer solution is passed through a first filter, 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.
