Abstract

Thermoplastic molding materials contain, as essential components, PA1 A) 10-80% by wt. of a copolyester based on polyalkylene terephthalates, which contains from 5 to 25% by weight, based on A), of a dimeric acid of 7 to 52 carbon atoms as a co-component, and PA1 B) 20-70% by wt. of a mixture of carbonates of metals of the 2nd main group of the Periodic Table of Elements.
