Two types of novel biobased benzoxazine monomers (named as CBB and CBF, respectively) from cardbisphenol were synthesized by a solventless method. The chemical structure of the monomers was confirmed by FTIR, H-1 NMR and C-13 NMR spectra, etc. FTIR and DSC showed that CBB and CBF were thermally initiated and polymerized via ring-opening polymerization. As a result, the thin polybenzoxazine (named as PCBB and PCBF, respectively) films can be obtained. Dynamic mechanical analysis (DMA) indicated that the glass transition temperatures (T-g) of PCBB and PCBF were 94 degrees C and 121 degrees C, respectively. Thermogravimetric analysis (TGA) demonstrated that the thermal stability of PCBF was better that of PCBB. Both PCBB and PCBF had low humidity absorption values.
