Dihydroxy capped triblock oligomers of 2, 2-dimethyltrimethylene carbonate (DTC) and ε-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.
- Rare earth catalyst,
- block oligomer,
- 2,2-dimethyltrimethylene carbonate,
