| Abstract: | The reaction kinetics between diazide(4,4′‐biphenyl dibenzyl azide) and internal diyne(bis2‐(phenyl)ethynyl]dimethylsilane) was studied in this study by means of differential scanning calorimetry (DSC) and nuclear magnetic resonance spectra (1H NMR). DSC was carried out to analyze the reaction in bulk polymerization condition, whereas 1H NMR for solution reaction polymerization. The apparent activation energy (eα) calculated by Kissinger's method was 90.83 kJ/mol, which was confirmed by Friedman's method, and 87.67 kJ/mol by 1H NMR, respectively. The polymerization between the diazide and internal diyne was the second‐order reaction based on calculation from both of DSC and 1H NMR. |
