The ambient-temperature self-healing potential of a poly(methacrylate) network, containing reversible furan- maleimide Diels-Alder crosslinks, is studied. A reversible bis(methacrylate) monomer, containing Diels-Alder bonds, is synthesized and characterized by means of 1H NMR spectroscopy. Subsequent polymerization via UV-cure yields a reversible polymer network, consisting of thermoplastic poly(methacrylate), crosslinked by Diels-Alder bonds. Characterization of the polymer network via high-resolution solid-state 13C NMR indicates that undesirable side reactions, such as the formation of irreversible maleimide homo- and copolymers, are prevented by protecting the maleimide functionality in the Diels-Alder adduct. The thermal reversibility of the polymer network is studied by means of Fourier transform infrared spectroscopy and differential scanning calorimetry, and it is confirmed that the reversibility of the Diels-Alder reaction remains during several thermal cycles between
