| 英文摘要 | The curing process of dendritic polymer pamam with bis-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 k(1), k(2) 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 e-1 and e-2 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. |
