Thermoplastic molding compositions comprising, based on the components A) to F), A) from 5 to 70% by weight of at least one graft copolymer A) made from an elastomeric graft base with a glass transition temperature below 0° C., and a graft made from a styrene compound, and acryonitrile or methacrylonitrile or a mixture of these and, where appropriate, further monoethylenically unsaturated monomers, B) from 29 to 90% by weight of a hard copolymer made from at least one styrene compound, acrylonitrile or methacrylonitrile or a mixture of these and, where appropriate, further monoethylenically unsaturated monomers, C) from 0 to 5% by weight of at least one three-block copolymer X-Y-X having a central block Y made from propylene oxide units and having terminal blocks X made from ethylene oxide units, D) from 0.01 to 5% by weight of at least one butylated reaction product of p-cresol with dicyclopentadiene, E) from 0.01 to 5% by weight of at least one thiocarboxylic ester, F) from 0.01 to 5% by weight of at least one alkali metal salt or alkaline earth metal salt of a C6-C20 carboxylic acid, and G) from 0 to 30% by weight, based on components A) to G), of other conventional additives,where the weathered db* value of the molding compositions is below +5.0 after 100 hours of exposure to light and weathering to ISO 4892/2, method A, black-panel temperature 65° C., using the CIE-Lab color system, to DIN 6174 and DIN 5033. |
