    摘要: A subject-matter of the present invention is novel polyglycidyl azides of general formula (I): in which: R1 represents an alkylene chain comprising 2 to 4 carbon atoms, R2 represents an alkyl chain comprising 1 to 4 carbon atoms, x represents an integer such that 4≦x≦10. These compounds are not detonatable and are of use in particular as energetic plasticizers in solid pyrotechnic compositions. They can be obtained according to a 3-stage process starting from epichlorohydrin by preliminary synthesis of polyepichlorohydrin with a hydroxyl terminal group of formula (II): then acylation of this compound in order to obtain a polyepichlorohydrin with an acyloxy terminal group of formula (IV): and then azidation of this compound.
