摘要

Abstract

The biphenol based discrete ion-pair rare earth complexes

[Ln(EDBP)

(DME)Na(DME)

] [Ln = Er

]

were prepared and used as catalysts for the ring-opening polymerization (ROP) of 2

2-dimethyltrimethylene carbonate (DTC). Three complexes show moderate activities for the polymerization

and the catalytic activities increase in the following sequence: (Yb

Sm). The effect of different ratios of [DTC]/[Ln]

polymerization temperature and time on the polymerization was investigated. Moreover

PDTC without ether unit developed from possible CO

elimination was prepared.
