Circular Nonisocyanate Polyhydroxyurethane Networks with High Stiffness and Thermal Reprocessability through Furan–Maleimide Diels–Alder Chemistry
High-performance nonisocyanate polyurethanes with circular end-of-life options remain difficult to obtain because polyhydroxyurethane networks often combine limited mechanical performance with poor reprocessability. Here, furan-functionalized polyhydroxyurethane oligomers were crosslinked with a trifunctional maleimi...
