Abstract
Epichlorohydrin is polymerized with an active hydrogen-containing initiator and the resulting secondary hydroxyl-containing polyepichlorohydrin is further reacted to produce a hydroxyl-terminated polyepichlorohydrin product having chains terminating in a primary hydroxyl group, said polyepichlorohydrin product being reactable with an inorganic azide to produce a poly(glycidyl azide) product useful as a binder for solid rocket propellants.
