Synthesis of benzoxazine-based phenolic resin containing furan groups

A novel benzoxazine-based phenolic resin containing furan groups (PFB) was synthesized via simple two-step reactions and the structure of PFB was confirmed by FTIR and 1H NMR spectra. Differential scanning calorimetry (DSC) showed that the polybenzoxazine cured from PFB had good heat resistance and lower polymerization temperature compared with that of benzoxazine-based phenolic resins.
