    摘要: The present invention discloses new catalyst systems based on trivalent metal complexes of Formula I, which can facilitate the stereospecific ring-opening polymerization of (rac)-β-Butyrolactone (rac-BBL). Also provided is a process for the stereospecific synthesis of aliphatic polyesters using the catalysts of Formula I, including alcohols and polyols as chain-transfer agents to facilitate immortal ring-opening polymerization.
