摘要：The phenyinitrile functional benzoxazine monomers, 3-phenyl-3,4-dihydro-6-nitril-2H-1,3-benzoxazine (NBen-a) and 4,4'-bis(3,4-dihydro-6-nitril-2H-1,3-benzoxazine-3-yl)phenylether (NBen-De), were synthesized and characterized by Fourier transform infrared (FTIR) spectroscopy and proton nuclear magnetic resonance (H-1-NMR). The curing behaviors of NBen-a and NBen-De were characterized by differential scanning calorimetry (DSC) and FTIR. Thermal stability and dynamic mechanical properties of the cured NBen-a and NBen-De were investigated using thermogravimetric analysis (TGA) and dynamic mechanical analysis (DMA). The cured NBen-a and NBen-De showed glass transition temperature (T-g), the thermal stability improved as compared to the analogous polybenzoxazine without phenyinitrile group.
