摘要

Abstract

L-lactide (LLA) homopolymerization and copolymerization with

-caprolactone (CL) in toluene initiated by tetrahydrosalen-supported yttrium borohydride complex were systematically investigated. A possible mechanism of LLA homopolymerization was proposed according to the

H-NMR result. In addition

PCL-

-PLLA copolymers were synthesized by sequential addition of monomers and their structure was characterized by GPC

H-NMR and

C-NMR.
