Synthesis and characterisation of tri- and tetraethyleneglycoldiazide for their use as energetic plasticisers

摘要

Tri- and tetraethyleneglycoldiazide (TEGDA and 4EGDA) were synthesised from their corresponding chlorides by a reaction with sodium azide in water with a phase transfer catalyst in batches up to one kilogram of the product. The influence of the plasticisers on the glass transition temperature of different glycidyl azide polymer (GAP) formulations was evaluated by differential scanning calorimetry (DSC). Their compatibility to different fillers was evaluated by heat flow calorimetry (HFC). The solubility of ammonium dinitramide (ADN) in the plasticisers was also measured.
