A bifunctional five-membered cyclic carbonate was synthesized from carbon dioxide and diglycidyl terephthalate, and its polyaddition with alkyl diamines were carried out in DMF at room temperature to obtain the corresponding poly(hydroxyurethane)s with M(n)s in the range of 6300-13200 in good yields. The structures of the obtained polymers were confirmed by IR and NMR spectroscopy and their glass-transition and decomposition temperatures were observed at 3-29 degrees C and 182-277 degrees C, respectively.
