In this work, several furanyl diols with amide, imide, or amine groups were synthesized, each diol was subsequently polymerized with 4,4′-dicyclohexylmethane diisocyanate and polytetramethylenene ether glycol to prepare polyurethanes. Bis(4-maleimidophenyl) methane was then added as a cross-linker to give self-healing polyurethanes. DSC and DMA analysis were used to measure the DA/rDA temperature of these polyurethanes with different chemical structures. It was demonstrated that the polyurethane prepared from amide furanyl diol had the highest DA/rDA temperature, followed with the order of amide > imide > amine. This expands the versatility of monomers that have different self-healing activity, which is expected to have the application for preparing various polyurethane coatings.
