We have successfully carried out living anionic ring‐opening polymerization of ethylene oxide in the mixture of benzene/dimethyl sulfoxide (DMSO) using authentic n ‐butyllithium with potassium tert ‐butoxide as the initiating system. The resulting poly(ethylene oxide) (PEO) used for biomedical applications could be readily modified by chain‐end functionalizations. It was possible to control the molecular weight of PEO as well as to achieve quantitative chain‐end functionalizations of PEO.
