A Schematic diagram of the recycling process of PAOM. B Digital photos of rDDF–OH, rBDO, rFDCA, and rDMFD obtained from the depolymerization of PAOM-4 in the H2O/BDO/NaOH system. C–F 1H NMR spectra in DMSO-d6 and LC analysis of FDCA/rFDCA and DMFD/rDMFD obtained from the recycling experiment. G 1H NMR spectrum of rDDF–OH in DMSO-d6. H, I Stress–strain curves, tensile strength, and elongation at break of PAOM-4 and rPAOM-4. The bar represents the mean value for three individual experiments, and the error bar is the standard deviation based on three individual experiments. J Synthesis process of up-PU and its application as an adhesive. K FTIR spectrum of up-PU. L Adhesive strength of up-PU on Al and PA plates. The bar represents the mean value for three individual experiments, and the error bar is the standard deviation based on three individual experiments.
