A thermoplastic molding composition having improved mechanical properties is
disclosed.
The composition contains (A) aromatic polycarbonate and/or polyester carbonate
(B) at least one graft rubber, obtained by emulsion polymerization of styrene and
acrylonitrile in the presence of at least two rubber latices of type (B1) and (B2)
where (B1) has a particle diameter d50 of 350 nm, a particle
size distribution range of 30 nm to 100 nm, and a gel content of 70 wt. %, and
(B2) has a particle diameter of 350 nm, a particle size distribution range
of 50 nm to 500 nm, and a gel content of 70 wt. %, and the difference in
the average particle diameter of B1 and B2 is 50 nm, (C) an optional copolymer
of styrene and or acrylonitrile and for methyl methacrylate and/or N-substituted
maleinimide, and optionally (D) flame retardant as well as optionally conventional additives.
