Abstract
A new method for the preparation of Glycidyl Azide Polymer (GAP) was developed at DREV. This improved process involves the synthesis of GAP in only one step, directly from the Epichchlorohydrin (ECH) monomer. The reaction is conducted in Dimethyl Formamide (DMF) at 90C in less than 8 h and without using any catalyst. The single-step synthesis of GAP according to this novel method is less costly than the American process developed by Rockwell, since the reaction is carried out in a much shorter time and requires relatively lower amounts of solvent (DMF) and sodium azide. The effect of the experimental conditions on the physico-chemical properties of the GAP product was also investigated. GAP prepared according to this process was of low molecular weight type (MW approximates to 500) and consequently could be used mainly as an energetic plasticizer. GAP had a hydroxyl functionality of 1.2 and a glass transition temperature of -70 + or - 5C.
