ABSTRACT:
The invention relates to thermoplastic moulding compositions consisting of (A) 65-97% by weight of a polyamide and (B) 3-5% by weight of a graft rubber having a gel content of at least 50% by weight and a glass transition temperature below -20.degree. C., the sum of the components A and B being 100% by weight, containing 0.1-1% by weight, preferably 0.25-0.8% by weight, relative to the sum of A and B, of tetrafluoroethylene polymers, and to a process for their preparation.
