英文摘要: A series of hybrid polyhydroxyurethane (PHU) materials were prepared from CO2, polypropylene glycol diglycidyl ether, amines, and bisphenol-A diglycidyl ether (BADGE). Firstly, the five-membered cyclocarbonate (5CC) as the CO2-sourced monomer was synthesized by a cycloaddition reaction from CO2 and polypropylene glycol diglycidyl ether at 120 °C under 10 bar CO2 pressure in the presence of an amberlyst catalyst. The selectivity of 5CC was confirmed through an analog computation method based on the results of 1H NMR. Then, 5CC was reacted with excessive amines to produce the -NH2 terminated pre-polymers. Finally, the pre-polymers reacted with BADGE to produce hybrid PHU materials. The effect of amine type and BADGE content on the properties of PHUs was studied by means of Fourier transform infrared spectra, dynamic mechanical thermal analysis, and thermogravimetric analysis and solvent swelling test. The results indicated that introducing BADGE as a chain extender not only enhances the gelation rate of PHU, but also improve the mechanical and thermal properties of PHU materials. © 2016 Published by Elsevier Ltd.
