Lanthanum heterocyclic Schiff-base complex initiated ring-opening polymerization of ε-caprolactone
摘要:
Lanthanum complex supported by the heterocyclic Schiff-base ligand of N-(2-pyridyl)-3, 5-di-tert-butyl-salicylaldimine was prepared and employed for the ring-opening polymerization (ROP) of ε-caprolactone (ε-CL). The polymers obtained with this initiator showed a unimodal molecular weight distribution implied that only one active species was present. Mechanism study revealed that the polymerization proceeds via acyl-oxygen bond cleavage.
