초록

The chemical stability of typical polybenzoxazines based on bisphenol-A and epoxy/novolac resins has been studied. Using proton nuclear magnetic resonance ('H-NMR) spectroscopic analysis of the polybenzoxazine model dimers, differential scanning calorimetry (DSC), and fourier transformed infrared (FT-IR) spectroscopy of the residue degraded from 2,2-bis(3,4-dihydro-3-methyl-2H-1,3-benzoxazine)propane (B A-m) polybenzoxazine, it is proposed that the basicity of the primary amines play an important role in the interactions which take place between the acid and polybenzoxazine. The stability of 2,2-bis(3,4-dihydro-3-phenyl-2H-1,3-benzoxazine)propane (BA-a) polybenzoxazine in various acids is superior to the stability of other resins including Novolac.
