Production process of impact modified thermoplastic molding composition with improved processing and impact strength

摘要

The present invention is a thermoplastic molding composition comprising thermoplastic copolymer A, graft copolymer B and optionally additional polymer component C, as well as any additional additive K, wherein the preparation of the graft copolymer is carried out via emulsion polymerization , At least one surfactant S2 is used in the grafting step of the emulsion polymerization at a volume concentration in the range of 0.46 to 0.75 mol/m ³ , based on the volume of the obtained graft copolymer B latex particles, the graft copolymer It relates to a thermoplastic molding composition having an average particle diameter D _w of the latex particles of B in the range of 60 to 800 nm.
