Blow-Moldable Polyamide Compositions

Abstract

Thermoplastic molding compositions comprising A) from 10 to 99.7% by weight of a polyamide, B) from 1 to 30% by weight of an impact modifier, C) from 0.1 to 10% by weight of a copolymer of C1) from 50 to 95% by weight of styrene or substituted styrenes of the general formula I or a mixture of these in which R is an alkyl radical having from 1 to 8 carbon atoms or a hydrogen atom and R1 is an alkyl radical having from 1 to 8 carbon atoms and n has the value 0, 1, 2, or 3, and C2) from 5 to 50% by weight of structural units derived from one or more dicarboxylic anhydrides, D) from 0.001 to 20% by weight of iron powder, E) from 0.05 to 3% by weight of a copper-containing stabilizer, F) from 100 ppm to 5% by weight of a phosphorus-containing, inorganic acid or salts thereof or ester derivatives thereof or a mixture thereof, G) from 0 to 2% by weight of a polyethyleneimine homo- or copolymer, H) from 0 to 60% by weight of further additives, where the total of the percentages by weight of A) to H) is 100%.
