Thermoplastic molding materials based on an optionally rubber-modified vinylaromatic polymer comprise an antistatic polyether and a phenolic antioxidant selected from octadecyl 3-(3,5-di-t-butyl-4-hydroxyphenyl)propionate and 2,4-dimethyl-6-(1-methylpentadecyl)phenol. Thermoplastic molding materials comprise: (A) 95-99.9 parts by weight (pbw) of an optionally rubber-modified vinylaromatic polymer comprising: (a) 0-100 wt.% of a graft copolymer consisting of 10-95 wt.% rubber and 5-90 wt.% of grafted styrene, alpha -methylstyrene, ring-substituted styrene, methyl methacrylate, (meth)acrylonitrile, maleic anhydride and N-substituted maleimide, where the rubber has a glass transition temperature below 10 deg C and in the form of at least partially crosslinked particles with a mean diameter of 0.05-20 mu m; and (b) 0-100 wt.% of a thermoplastic polymer of styrene, alpha -methylstyrene, ring-substituted styrene, methyl methacrylate, (meth)acrylonitrile, maleic anhydride and N-substituted maleimide; and (B) 0.1-5 pbw of a mixture of: (c) a polyalkylene ether, optionally modified with radical formers or acid groups, with a number-average molecular weight of 500-20,000; and (d) a phenolic antioxidant selected from octadecyl 3-(3,5-di-t-butyl-4-hydroxyphenyl)propionate and 2,4-dimethyl-6-(1-methylpentadecyl)phenol; where the (c):(d) weight ratio is 1-20:1.
