6-tri(hydroxylphenylmethylamino)-s-trizine(MFP)was synthesized and its structure was characterized by infrared spectroscopy(IR)

1H-NMR and element analysis．The kinetics and mechanism for curing of diglycidyl ether of bisphenol A(DGEBA)with MFP were studied by differential scanning calorimeter(DSC)and in situ IR．The results of dynamic DSC thermograms showed that two peaks presented in the proceeding of reaction because of two kinds of active hydrogen in the structure of the MFP molecule

and the first exothermic peak resuhed from the the reaction of amine with epoxy group(Ea=70．5 kJ·mol-1

calculated by Kissinger method)and the second exothermic peak resulted from the reaction of hydroxyl with epoxy group(Ea=86．5 kJ·mol-1

Kissinger method)by comparing with the curing process of DGEBA with a model compound 2

6-tri(o-methylhydroxyphenyl—methylamino)-s-trizine(MFoP)．The results of in situ FTIR confirmed this conclusion．
