Abstract:The objective of this paper is to conduct a comparative analysis of sesamol-based benzoxazine monomers derived from anilines with an ethynyl substituent in a different position and to obtain some laws to guide the design of thermosets. The synthesis of bio-benzoxazine monomers (S-a, S-oea, S-mea, and S-pea) via a one-step method from sesamol, a biomass monophenol, in the presence of polyformaldehyde by combining four different amines (aniline, ortho-ethynyl aniline, meta-ethynyl aniline, and para-ethynyl aniline), respectively. The structures of four new benzoxazine monomers were characterized
