Reaction with sodium azide (50 °C) requires a mild acid such as ammonium chloride as the proton source for quenching the alkoxide anion. The reaction generates polymeric azides in high efficiency. A subsequent modification of the azide groups through copper-catalysed ‘click’ reaction then gives access to functionalised polymers.
