Abstract: The present invention relates to a process for producing a thermoplastic molding composition and articles made thereof having improved surface quality, in particular improved surface quality after exposure to warm-humid environmental conditions. The thermoplastic molding composition comprises a thermoplastic polymer A, a graft copolymer B obtained by emulsion graft polymerization and optionally a further polymer component P, as well as optional further components/additives K, wherein at least one crystallization additive C, selected from phosphate compounds having 1 to 25 phosphate units, organic acids and salts thereof, is added during or after the preparation of the graft copolymer B.

Abstract: The invention relates to a process for producing graft copolymers based on acrylonitrile-butadiene-styrene copolymers (ABS), wherein the graft copolymers may be dewatered particularly readily after production and precipitation and have a low residual moisture content after centrifugation. The invention further relates to a process for producing thermoplastic molding materials using the thus obtained ABS graft copolymers.
