1H-NMR spectra of (A) RCPhC1-NB and (B) RCPhC1-MA. The characteristic peaks associated with norbornene (both the endo-form (6.41 and 6.08 ppm) and the exo-form derivatives (6.36 and 6.34 ppm)) and methacrylamide (5.8 and 5.5 ppm, which correspond to the vinyl protons of the methacrylamide functionalities introduced) are highlighted, respectively.
