Abstract

Thermoplastic molding compositions comprise PA1 A) from 5 to 97.9% by weight of a vinylaromatic polymer with syndiotactic structure, PA1 B) from 2 to 90% by weight of a low-viscosity polyamide with a viscosity number VN in the range from 50 to 150 ml/g and PA1 C) from 0.1 to 50% by weight of a polar-group-modified polyphenylene ether.
