Thermoplastic molding compounds, provided with an antistatic agent which exhibit improved color stability during processing

A thermoplastic molding composition comprising

• I.) 99.90 to 95 parts by weight of resinous component that contains
• A) 0 to 100 % by weight of one or more graft polymers of 10 to 95% by weight (with respect to A) of an at least partially crosslinked rubber having glass transition temperatures <10° C., said rubber having an average particle diameter of 0.05 to 20 μm, and 90 to 5% by weight (with respect to A) of a grafted phase polymerized of at least one member selected from the group consisting of styrene, α-methyl styrene, nucleus-substituted styrene, methyl methacrylate, (meth)acrylonitrile, maleic anhydride and N-substituted maleimide and
• B) 100 to 0% by weight of a thermoplastic vinyl (co)polymer polymerized of at least one member selected from the group consisting of styrene, (α-methylstyrene, nucleus-substituted styrene, methyl methacrylate, acrylonitrile, methacrylonitrile, maleic anhydride and N-substituted maleimide, and
• II.) 0.10 to 5 parts by weight of a mixture of
• a) at least one component having a number average molecular weight of 500 to 20,000 selected from the group consisting of unmodified polyalkylene ethers, polyalkylene ethers modified with radical-formers, and polyalkylene ethers modified with acid groups, and
• b) at least one phenolic antioxidant selected from the group consisting of octadecyl-3-(3′,5′-di-tert.-butyl-4-hydroxyphenyl)propionate and 2,4-di-methyl-6-(1-methylpentadecyl)-phenol,
• wherein the ratio by weight of (a):(b) is 20:1 to 1:1.
