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.

Abstract: The invention relates to a process for producing a stabilizer dispersion S, wherein the stabilizer dispersion is an aqueous composition comprising at least one phenolic stabilizer A, at least one thio co-stabilizer B, at least one surfactant C and at least one silicon oil component D. Further the present invention is directed to a process for producing a thermoplastic moulding composition, in particular an composition based on acrylonitrile butadiene styrene copolymers (ABS), using the stabilizer dispersion S.
