Abstract
The invention relates to new aromatic/aliphatic and/or alicyclic copolyester amides with high molecular weights, without crosslinking. A subsequent solid phase condensation is avoided or is greatly limited in time. The occurrence of thermal decomposition reactions, dark discolorations of the polymers as well as the formation of block structures are avoided.
