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.

Abstract: The present invention relates to a process for the production of styrene graft copolymers comprising addition and graft copolymerization of styrene monomers A1 and vinyl cyanide monomers A2 to a graft base B where the ratio by mass of A1 to A2 in the monomer feed at the end of the monomer feed time is lower than the ration by mass integrated over the entire monomer feed time. The present invention further relates to a graft copolymer obtainable by a process according to the invention, a molding composition comprising such a graft copolymer, and a molding obtained from such a molding composition.
