摘　　要：Dihydroxy capped triblock oligomers of 2, 2-dimethyltrimethylene carbonate (DTC) andε-caprolactone (CL) with number-average molecular weight from 3,000 to 12,000 g/mol have beensynthesized 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 thedesign of new polymeric materials.

关 键 词：Rare earth catalyst block oligomer 2 2-dimethyltrimethylene carbonate ε-caprolactone.
