Abstract	Benzoxazine/epoxy copolymers were prepared by solution blending bis(4-(8-allyl-2H-benzo[e][1,3]oxazin-3(4H)-yl)phenyl)methane (oAP-ddm) with bisphenol-A type novolac epoxy resin (bis-ANER), followed by thermally polymerization of the blend. The copolymerization behavior of oAP-ddm/bis-ANER was investigated by Fourier transform infrared spectroscopy and differential scanning calorimetry (DSC). With the increasing of bis-ANER fraction, the exothermic peak in DSC curve changes from one to two overlapped peaks, and the second peak shifts to higher temperatures. Dynamic mechanical analysis results show that a single peak appears in each tan δ curve of the oAP-ddm/bis-ANER copolymers. With the bis-ANER content increasing, the storage modulus and the peak temperature of tan δ peak increase, whereas the tan δ peak height decreases. Thermogravimetric analysis results indicate that the onset temperatures of mass loss and the char yields at 800 °C of the oAP-ddm/bis-ANER copolymers decrease with the increase of bis-ANER content.
