Abstract: An emulsion polymerization process for preparation of ABS graft copolymer latex having reduced residual monomer content, wherein a grafting step c) comprises the steps: c1): feeding of 10 to 45 wt.-% of styrene and acrylonitrile in one portion to agglomerated butadiene rubber latex and addition of redox system initiator, then polymerization; c2): feeding remaining monomers in portions or continuously and further addition of redox system initiator; c3): addition of inorganic free radical initiator and continuation of polymerization, leads to ABS graft copolymers and thermoplastic molding compositions which can be used in the automotive industry.
