Abstract: The present invention is directed to a process for the production of graft copolymer compositions which are based on acrylonitrile-styrene-acrylate (ASA) or acrylonitrile-butadiene-styrene (ABS) graft copolymers. The graft copolymers compositions are obtained by emulsion polymerization and afterwards precipitation, dewatering, drying and optionally cooling of the dried graft copolymer powder, wherein the graft copolymer B powder obtained is mixed with an aeration gas, preferably air and/or nitrogen, wherein the bulk density of the graft copolymer B powder is equal or less than 98.5% of the bulk density of the non-aerated graft copolymer B, during the whole aeration step. The graft copolymer powders show higher powder flowability and less tendency of caking during storage, for example in a silo.
