Abstract Coordinated anionic ring‐opening polymerization of ε‐caprolactone in the presence of alcohols enables functional oligocaprolactones to be obtained easily in a single step. As observed by NMR and Maldi Tof mass spectroscopy, the functionalization of the oligomers, as well as the molecular weight distribution, depend strongly on the chemical structure of the alcohol. Hydroxy telechelic polymers can also be used as transfer agents. Finally, it was found that the chemical nature of the alcohol has a great influence on the kinetics, which suggests a coordination of this moiety on the Lewis site, during all the reaction.
