Abstract New aspects of anionic polymerization of 4‐membered lactones are presented, attention being paid to regioselectivity of ß‐lactones ring‐opening reactions. It has been demonstrated that supramolecular complexes of alkali metal alkoxides used as initiators enable control of lactones polymerization, and due to anion activation yield polymers with specific molecular architecture. Synthesis of the analogue of natural polymer poly(3‐hydroxybutyrate) via anionic polymerization of ß‐butyrolactone is discussed.
