The catalytic activity of alkali (Na, K) enolates of various β-keto carbonyl compounds for the ring-opening polymerization (ROP) of cyclic esters was investigated. The effect of neutral secondary ligands on reaction control at high conversion (&gt;95%) was probed. The ready availability of these new catalysts and the high-degree of control (PDI &lt;1.2) over ring-opening polymerization reactions makes this an attractive, alternative method for accessing aliphatic polyesters.
