Abstract: The invention relates to thermoplastic moulding materials containing a mixture of (A) between 30 and 69 wt. %, in relation to the sum of the constituents (A), (B) and (C), of a methylmethacrylate polymer, (B) between 30 and 69 wt. %, in relation to the sum of the constituents (A), (B) and (C), of a copolymer that can be obtained by the polymerisation of a vinylaromatic monomer and a vinylcyanide, and (C) between 1 and 40 wt. %, in relation to the sum of the constituents (A), (B) and (C), of a graft copolymer that can be obtained from (C1) between 60 and 90 wt. %, in relation to (C), of a core, (C2) between 5 and 20 wt. %, in relation to (C), of a first graft envelope consisting of a vinylaromatic monomer, an alkylmethacrylate and optionally a cross-linking monomer, and (C3) between 5 and 20 wt. %, in relation to (C), of a second graft envelope consisting of an alkyl(meth)acrylate polymer, on the proviso that the quantitative ratio of (C2) to (C3) is between 2:1 and 1:2. The invention is characterised in that the average particle size D50 of the core (C1) is between 50 and 250 nm, the average particle size D90 of the core (C1) is between 60 and 1000 nm, the average particle size D90 of the core (C1) being larger than the average particle size D50 of the core (C1), by a factor between 1.15 and 20, and the core (C1) can be obtained by the polymerisation of a monomer mixture comprising (C11) between 65 and 89 wt. %, in relation to (C1), of a 1,3-diene, (C12) between 10 and 34.9 wt. %, in relation to (C1), of a vinylaromatic monomer, and (C13) between 0.1 and 5 wt. %, in relation to (C1), of an agglomeration polymer. The invention also relates to a method for producing said moulding masses, to the use thereof, and to the moulded bodies obtained therefrom.
