a Photographs of the depolymerization of polymer networks, the separation and recycling procedures of BMA and TMEN monomers by the liquid-liquid extraction method (scale bar: 1 cm). b 1H NMR spectra of pristine and recycled BMA. c 1H NMR spectra of pristine and recycled TMEN. d ESI-MS spectra of pristine and recycled BMA. e ESI-MS spectra of pristine and recycled TMEN. f FT-IR spectra of BMA-TMEN and repolymerized BMA-TMEN from recycled monomers. g Stress-strain curves of BMA-TMEN and repolymerized BMA-TMEN from recycled monomers.
