Abstract

A moulding composition consisting of: PA1 From 60 to 93 parts, by weight, of a polyamide; PA1 From 6 to 30 parts, by weight, of a polyethylene; and PA1 From 1 to 20 parts, by weight, of a copolymer of an aromatic vinyl compound, an .alpha., .beta.-unsaturated mono- and/or di-carboxylic acid or an anhydride thereof, free acid groups optionally being neutralized by a mono- and/or poly-amine or with ammonia, and an ester of the said mono- and or di-carboxylic acid.
