## 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
