【Abstract】 A novel thermal polymer monomer,which called Bis(3,4-dihydro-3-phenyl-1,3-benzoxazine)(BZ),was synthesized successfully in the solvent.With the characterization of BZ by FT-IR,the curing reaction behavior of BZ was investigated extensively using the differential scanning calorimetry(DSC)with four different dynamic scans,the activation energy and the order of the reaction are determined using one kind of difference-differentiation computational method.The activation energy for the reaction is observed in the range 429～497kJ/mol and the order of the reaction is observed to be 1.78～0.58.更多还原
