60557-3065D Abstract of the Disclosure The invention relates to a normally liquid, polyglycidyl azide product having a low polydispersity which is produced by reacting a polyepichlorohydrin product with an inorganic azide, said polyglycidyl azide product comprising predominantly secondary hydroxyl-terminated polyglycidyl azide polymer, said polyepichloro- hydrin product having a number-average molecular weight of a least 2000 and a polydispersity of less than 1.2, and comprising predominantly secondary hydroxyl-terminated polyepichlorohydrin polymer and essentially no non-hydroxyl functional cyclic ether oligomer, said polyepichlorohydrin product being made by poly- merizing epichlorohydrin in the presence of anhydrous stannic chloride catalyst, a strong carboxylic acid co-catalyst, and an alcohol as an initiator. Polyurethanes prepared from such azide derivatives are useful as a binder for solid rocket propellants.
