Zusammenfassung:	THE USE IS CLAIMED OF FILAMENT-FORMING CHAIN-BRANCHED POLYESTERS AND COPOLYESTERS WITH A RELATIVE MOLECULAR WEIGHT OF > 10000 ARE PROVIDED, OBTAINED BY CONDENSING INTO THE POLYESTER-FORMING STARTING COMPONENTS 50-500 PPM OF ONE OR MORE CHAIN-BRANCHING AGENTS ADDED DURING THE POLYESTER MANUFACTURE AND HAVING THE GENERAL FORMULA ( FORMULA 1 ) WHERE N = 2 - 4. THEY ARE EXCELLENTLY SUITED FOR HIGH-SPEED SPINNING OF TEXTILE AND INDUSTRIAL YARNS WITH WINDING SPEEDS OF 2500-10000 M/MIN, FOLLOWED BY CONVENTIONAL DRAWING OR TEXTURIZING PROCESSES.
