The boric acid ethanolamine ester(BAE) was synthesized using boric acid and ethanolamine. The synthesis of benzoxazine contained boron(BAE-BOZ) was synthesized by using BAE, phenol and paraformaldehyde. The BAE-BOZ are mixed with epoxy resin in different proportions, and then cured by high temperature. Using FT-IR, ~1H NMR and ~(13)C NMR analysis of the chemical structure of BAE-BOZ, proved that the target product has been synthesized. Curing properties on BAE-BOZ was studied with DSC, the thermal stability...
