The curing process of dendritic polymer PAMAM with his—phenol A epoxy resin was investigated using isothermal differential scanning calorimetry(DSC)

the mechanism of this reaction was autocatalytic．The data of two reaction rate constants kl

k2 and reaction orders m

n were obtained from Kamal equation．The overall reaction order m+n was between 2．07 and 2．29

the apparent activation energies of E1 and E2 were 59．79 kJ／mol and 56．51 kJ／mol．respectively．The reaction entered into a diffusion controlled stage at the conversion of 50％

experimental data and theoretic curve had deviation at this time．The reaction conversion

at which the deviation occurred

decreased with lowering curing temperature．
