Characterization of EMO and MEMO. 1H NMR spectra were obtained using a Bruker 11.7 T Avance III spectrometer operating at 500 MHz for 1H, equipped with a TXI gradient probe. Deuterated chloroform (CDCl3) was used as solvent for all samples. The Degree of Modification (DoM) was calculated using the CH proton from the glycerol as a reference. Based on that, the epoxides and the methacrylates peaks were integrated to evaluate the average number of functional groups on the oil molecules.
