## Abstract The synthesis of telechellcs of poly(ether‐ether‐sulfones) (PEES) is controlled by high‐resolution gel‐permeation chromatography to optimize for low content of side products. Under optimum conditions the bifunctional polymer‐homologous series is formed to 99,9%. These telechrcs were use
