The reaction of azido polymers with double and triple bonds of light olefins can lead to triazole and aziridine cycles formation on the azide bearing sites of the polymer. An experimental investigation of the burning behaviour of these modified polymers has shown that triazole substituted GAPs exhibit a higher burning rate at low pressure, which may be a desirable characteristic for ducted rocket applications. However, the chemical reaction of interest is highly exothermic and as such, it represents a significant safety risk when conducted in bulk. In order to reduce this risk, we have assessed the chemical kinetics of triazole formation by NMR spectroscopy and linked this information with DSC measurements to produce a safe procedure for the synthesis of GAP‐triazole polymer in a chemical reactor.
