Abstract

The present invention relates to thermoplastic moulding compositions of (A) 99.5 to 80% by weight, of at least one amorphous linear polyamide and (B) 0.5 to 20% by weight of at least one segmented thermoplastic elastomeric copolyester. These novel moulding compositions combine good toughness and hardness with good elongation and stiffness properties as well as good flowing properties of the molten material.
