A benzoxazine compound (FDP‐FBz), which possesses a fluorene group and two terminal furan groups, and itscorresponding cross‐linked polymer (CR‐FDP‐FBz) have been prepared using 4,4′‐(9‐fluorenylidene)diphenol (FDP), furfurylamine, and formaldehyde as precursors. The chemical structure of FDP‐FBz has been characterized with Fourier‐transform infrared and 1H nuclear magnetic resonance spectroscopies
Abstract A novel benzoxazine bearing fluorene and furangroup (B-bff) was prepared using 9,9-bis(4-hydroxyphenyl) fluorene, furfurylamine and formaldehyde as raw materials. The chemical structure of B-bff was characterized with FTIR, 1 H NMR, 13 C NMR, and elemental analysis. The curing reaction was investigated under non-isothermal differential scanning calorimetry (DSC) at different heating rates
