概要 Polyaddn. of bis(cyclic carbonate)s and hexamethylenediamine (I) or dodecamethylenediamine in DMSO or DMAc afforded corresponding poly(hydroxyurethane)s (PHU). The presence of H2O, MeOH, or EtOAc in the solvent had little effect on the Mn of the polymer obtained. Polyaddn. of bis(cyclic carbonate) bearing ester groups and I also afforded the corresponding PHU without aminolysis of the ester groups. PHU easily undertook crosslinking at room temp. by the treatment with diisocyanate or (iso-OPr)3Al. The gel crosslinked by (iso-OPr)3Al regenerated the original polymer at room temp. by treatment with HCl.
