摘要

Dihydroxy capped triblock oligomers of 2, 2-dimethyltrimethylene carbonate (DTC) and c-caprolactone (CL) with number-average molecular weight from 3,000 to 12,000 g/mol have been synthesized by alkyl glycol initiator in the presence of yttrium tri(2, 6-di-tert-butyl-4-methylphenolate)s (Y(OAr)(3)) catalyst. They are expected to be used as macroinitiators for the design of new polymeric materials.
