摘要

Optically active polyurethane was synthesized by the polyaddition of (2R

3R)-(+)-diethyl L-tartrate (DET)

4'-diphenylmethane diisocyanate (MDI) and polyethylene glycol (PEG) with variousmolecular weights at 60℃ in DMSO. The polymers were characterized by specific rotation

DSC and 1HNMR spectra.
