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
