Ring-opening polymerization of -caprolactone (CL) has been initiated with rare earth phenyl compounds in both bulk and solution. These rare earth phenyl initiators can give polycaprolactone (PCL) with high yield and high molecular weight. The polymerization mechanism is through a coordination-deprot
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
