Abstract:Ring-opening polymerization of ε-caprolactone (ε-CL) catalyzed by single component lanthanide tri(4-methylphenolate) s La(OMP) 3 ] was systematically studied. It has been found that La(OMP) 3 exhibits high activity and the polymerization has "living"characteristic. The initiation mechanism by La(OMP) 3 has been studied through oligomer end group analysis by NMR.
Keywords:ε-eaprolactone  ring-opening polymerization  lanthanide tri (4-methylphenolate) s
