Abstract

This invention relates to thermoplastic molding compositions with improved flowabilty based on a thermoplastic polyamide and on a copolymer composed of at least one olefin with at least one methacrylic ester or acrylic ester of an aliphatic alcohol, the MFI of the copolymer being not less than 50 g/10 min, and to a process for preparation of these molding compositions, and also to the use of the these molding compositions, for production of moldings for the electrical, electronics, telecommunications, motor vehicle, or computer industry, in sports, in medicine, in the household or in the entertainment industry.
