Provided is a method for a poly(GAP-co-THF)diol prepolymer in which THF monomer units are copolymerized to GAP, having high difunctionality, a reduced amount of cyclic oligomer side products having a small molecular weight, a wide copolymer composition and controlled molecular weight. The resulted poly(GAP-co-THF)diol prepolymer according to the present invention is used as a binder for a high-energy PBX or composite propellant, specifically used as a binder in the preparation of polyurethane having excellent mechanical properties.
