Abstract

A molding composition comprises from 80 to 99.9 parts by weight of thermoplastic polyester and from 0.1 to 20 parts by weight of a polyamide-polyamine graft copolymer, where the sum of the parts by weight of the polyester and of the graft copolymer is 100. The molding composition has improved flowability.
