Zusammenfassung:	Polyesters having at least 90%, by weight, of recurrent structural units corresponding to the following formula: and characterised by a relative viscosity eta rel of from 1.6 to 4.5 (determined at 25 DEG C. in CH2Cl2, c=5 g/l) are suitable for the production of films having highly advantageous performance characteristics, in particular high heat resistance.
