摘要：

Bisbenzoxazine of biphenol (BIPHO) was synthesized by condensing 0.05 mol biphenol, 0.2mol formaldehyde and 0.1 mol aniline. BIPHO was thermally polymerized via ring opening polymerization. Resultant cross-linked polymer (PBIPHO) was characterized by solubility, IR, H-1/NMR, DSC and TGA. BIPHO and PBIPHO followed three steps degradation. BIPHO undergoes selective ring opening polymerization over the temperature range 150-250 degrees C and degrades at elevated temperature. A 57-64% residue at 550 degrees C indicated high thermal stability of the cured polymer DSC thermograms of BIPHO and its polymer supported physico-chemical transformation. New thermosetting material may be useful for its specific applications to be searched.
