ABSTRACT = {In this work, a series of novel lignin-based bis-benzoxazine monomers were efficiently
synthesized by the reaction of renewable phenols: guaiacol, vanillyl alcohol, eugenol, vanillin
with ethylene diamine and paraformaldehyde. The chemical structures of these lignin-based
bis-benzoxazine monomers were confirmed by <sup>1</sup>H-NMR, <sup>13</sup>C-NMR and FTIR, indicating the
formation of benzoxazine ring. The obtained bis-benzoxazine monomers were cured via thermal
treatment. The curing behavior of these lignin-based bis-benzoxazine monomers were
compared and analyzed via differential scanning calorimetry (DSC), showing that Va-e
possessed higher ring-opening polymerization activity than G-e, while E-e and V-e had lower
curing activity than G-e.},
