POLYCARBONATE MIXTURE

The present invention relates to mixtures comprising (a) thermoplastic aromatic polycarbonates having &upbar& Mw (weight average molecular weight) of 10,000 to 200,000, preferably 20,000 to 80,000 (determined by measuring the relative viscosity eta rel in CH2Cl2 at 25 DEG C. and a concentration of 0,5 g per 100 ml CH2Cl2 (b) thermoplastic polymers of C1-C4-alkyl methacrylates having &upbar& Mw (weight average moleculr weight) of 10,000 to 1,000,000 (measured in dimethylformamide at 25 DEG C.) and (c) particulate graft polymers of methyl methacrylate onto a particulate, highly crosslinked alkyl acrylate-rubber which can optionally also contain a crosslinked diene rubber as an inner core, as well as to thermoplastic moulding compositions based on thermoplastic ABS resins or thermoplastic SAN resins which contain the three-component mixture (a)+(b)+(c).
