Ring-opening polymerization of lactone and lactide have been initiated with rare earth organoacid compounds, such as lanthanum acetate in bulk. The polymerization mechanism is in agreement with the "nonionic-coordination-insertion" mechanism, which involves the selective cleavage of the acyl-oxygen
