| 摘 要： | Lanthanide tris ( 2,6-dimethylphenolate ) s Ln ( ODMP)3 ] were used as iniliators for ring-opening polymerization of e-caprolac-tone (CL) for the first time. The influence of different rare earth elements and solvents was investigated. ^1H NMR spectral data of polycaprolactone (PCL) obtained showed that the poly-merization mechanism is in agreement with the coordination-in-sertion mechanism and the selective cleavage of the acyl-oxygen bond of CL.

| Abstract: | Lanthanide tris (2,6‐dimethylphenolate)s Ln(ODMP)3] were used as initiators for ring‐opening polymerization of s‐caprolactone (CL) for the first time. The influence of different rare earth elements and solvents was investigated. 1H NMR spectral data of polycaprolactone (PCL) obtained showed that the polymerization mechanism is in agreement with the coordination‐insertion mechanism and the selective cleavage of the acyl‐oxygen bond of CL. |
