1H NMR spectrum (in CDCl3 at 25 °C, expanded at 4.3–6.2 ppm) for (a) ME2 (monomer), (b) PE2 (ADMET polymer, run 15), and (c) DPE2 (after reaction with ethylene, run 49). The 13C{1H} NMR spectrum (in CDCl3 at 25 °C, expanded at 80–190 ppm) for (d) ME2 (monomer), (e) PE2 (ADMET polymer, run 15), and (f) DPE2 (after reaction with ethylene, run 49).
