摘要：
Non-isocyanate poly(hydroxyurethanes) (NIPUs) are a fast growing class of polymers prepared by an environmentally friendly method without the use of toxic phosgene and isocyanates. In this work, we report a one-step procedure to synthesize bis(2,3-dihydroxypropyl) ether dicarbonate from a commercially available diglycerol. The product was characterized by H-1 NMR, C-13 NMR, and FTIR spectroscopies and for the first time by X-Ray diffraction measurements. Enantiomers RR and SS of the obtained monomer were observed in the single crystal structure. The bis(cyclic carbonate) monomer was used as a precursor for the synthesis of various NIPUs. The NIPUs were prepared in a non-solvent process. Spectral, thermal and rheological properties of the NIPUs formed from ten various diamines were compared. (C) 2015 Elsevier Ltd. All rights reserved.
