Ring-opening polymerization of D,L-lactide has been successfully carried out by (ArO)₂Sm(THF)₄ (ArO=2, 6-ditertbutyl(4-methylphenoxo-) as catalyst for the first time. The catalyst contentration, monomer concentration and solvent showed a marked effect on the polymerization. The polymerization rate decrease with increase of monomer concentra-tion and decrease of catalyst concentration. The initiation mechanism has been discussed ac-cording to the results of end-group analysis of oligomer by IR. The active species are sup-posed to be a samarium enolate formed from the reaction of (ArO)₂Sm(THF)₄ with lactide.
- lactide,
- ring-opening polymerization,
