Abstract
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.
