    Abstract: Mouldings made of thermoplastic moulding masses contain (A) 30 to 99 wt %, relative to the total weight of the moulding mass, of a thermoplastic polymer, comprising, relative to (A): (a1) 50 to 100 wt % of a styrene compound of general formula (I), in which R?1 and R2¿ stand for hydrogen or C¿1?-C8 alkyl, or a (C1-C8-alkyl)ester of acrylic or methacrylic acid, or mixtures of the styrene compound and of the (C1-C8-alkyl)ester of acrylic or methacrylic acid; (a2) 0 to 40 wt % acryl nitrile or methacryl nitrile or their mixtures; and (a3) 0 to 40 wt % of one or several other monoethylenically unsaturated monomers different from (a2); (b) 1 to 70 wt %, with respect to the total weight of the moulding mass, of a graft polymer comprising, relative to (B): (b1) 30 to 90 wt % of a rubber-elastic grafted core made of a polymer with a glass transition temperature below 0 °C and obtained by copolymerising (b11) 50 to 99.99 wt %, with respect to (b1), of a (C1-C10-alkyl)ester of acrylic acid; (b12) 0.01 to 10 wt % of a polyfunctional, cross-linking monomer; and (b13) 0 to 40 wt % of one or several others monoethylenically unsaturated monomers different from (b11); and (b2) 10 to 70 wt % of a grafted sheath which contains, relative to (b2): (b21) 50 to 100 wt % of a styrene compound of general formula (I), in which R?1 and R2¿ stand for hydrogen or C¿1?-C8-alkyl; or a (C1-C8-alkyl)ester of acrylic acid or methacrylic acid; or mixtures of the styrene compound and of the (C1-C8-alkyl)ester of acrylic or methacrylic acid; (b22) 0 to 40 wt % acryl nitrile or methacryl nitrile or their mixtures; and (b23) 0 to 40 wt % of one or several other monoethylenically unsaturated monomers.
