WebThis study deals with synthesis of a reversible non-isocyanate polyurethane (NIPU) network in comparison with its epoxy counterpart. First, furfuryl cyclocarbonate ether (FCE) was synthesized by a green method of CO2 fixation (carbonation reaction) on furfuryl glycidyl ether (FGE; a bio-based compound). Afterwards, Diels-Alder (DA)….
