Benzoxazine monomer containing hydroxide synthesized with salicylal and p-aminophenol as the starting materials reacts with three phosphazene ring derivative containing active group(s) to produce the benzoxazine monomer containing three phosphazene ring structure, which in turn produce the product after curing. The T5% and T10% of the final product are 365℃ and 397℃, respectively, and the carbon residue rate of the product at 1000℃ is 48.2%. Compared with benzoxazine monomer containng no three phosphazene ring structure, the heat resistance and flame retardance increase significantly. |
