Abstract

The chloro-terminated polyethylene glycols (PEG(Cl) ₂) were synthesized under the conditions of polyethylene glycol (PEG) and thionyl chloride as raw materials, toluene as solvent, temperature 80°C.The azido-terminated polyethylene glycols (N ₃PEG) were synthesized from PEG(Cl) ₂ and sodium azide in N, N-dimethylformamide. The product was characterized by FT-IR, ¹H-NMR, ¹³C-NMR and DSC. FTIR showed disappearance of the chloride group and the characteristic absorbance of the azide group after the azide replacement. In the chloride and azide replacement reactions on PEG, no chain scission and other side reaction happened. N ₃PEG had a lower melting point than PEG. N ₃PEG is possible to be used as new binder of the composite solid propellant.
