Abstract

Abstract:

Abstract The polymerization characteristics of ε-caprolactone(CL) with lanthanum tris(2,6-di-tert-butyl-4-methylphenolate) at a low temperature was reported. The polymerization system shows some living character below -10 ℃. That is the length of polymer chain increases with the increase of the molar ratio of monomer to initiator or polymerization time. The block copolymers of CL and cyclic carbonate(TMC or DTC) were prepared after CL had been polymerized for a period at a low temperature and were characterized by GPC, DSC and 1H NMR.

Key words: Keywords ε-Caprolactone; Rare earth catalyst; Cyclic carbonate; Ring-opening polymerization
