Abstract:Biomass derivatives are a promising class of precursors for developing natural sustainable polymers. However, biobased polymers generally possess flammable characteristic and poor thermal stability, which seriously restrain their further applications. Herein, two biobased diamines (PDFA and CPDFA) were successfully synthesized using furfurylamine and benzaldehyde/cyanobenzaldehyde as starting materials. In addition, two novel bio-bisbenzoxazine monomers, S-cpdfa and S-pdfa, were obtained via the Mannich condensation reaction from paraformaldehyde, sesamol and PDFA/CPDFA. The chemical structure
