## Abstract A variety of single component rare earth aryloxides substituted by various alkyl groups [Ln(OAr)~3~] such as methyl, isopropyl, __tert__‐butyl have been surveyed in the ring‐opening copolymerization of 2,2‐dimethyltrimethylene carbonate (DTC) and __ε__‐caprolactone (__ε__‐CL). It was wo

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
