Branched azido copolymers

摘要

The invention disclosed relates to novel branched chain hydroxy-terminated aliphatic polyether copolymers containing glycidyl azide and an additional substituent selected from the group consisting of alkylene oxide, styrene azide oxide and glycidyl units, and a single step method for the manufacture thereof which involves reacting a solid rubbery material selected from epichlorohydrin/alkylene oxide copolymer (PEEC) and polyepichlorohydrin homopolymer (PECH) with various epoxide monomers. The novel polyether copolymers are useful as energetic binders in explosive and solid rocket propellant compositions.
