ABSTRACT The reaction kinetics between diazide(4,4′‐biphenyl dibenzyl azide) and internal diyne(bis[2‐(phenyl)ethynyl]dimethylsilane) was studied in this study by means of differential scanning calorimetry (DSC) and nuclear magnetic resonance spectra ( 1 H NMR). DSC was carried out to analyze the reaction in bulk polymerization condition, whereas 1 H NMR for solution reaction polymerization. The apparent activation energy ( e α ) calculated by Kissinger's method was 90.83 kJ/mol, which was confirmed by Friedman's method, and 87.67 kJ/mol by 1 H NMR, respectively. The polymerization between the diazide and internal diyne was the second‐order reaction based on calculation from both of DSC and 1 H NMR.
