2,2-Dinitropropyl propiolate ester(DNPP) was provided by esterification of propiolic acid and DNP-OH.1,2,3-Triazole-embedded copolyether polyol could be synthesized by Cu(Ⅰ)-catalyzed 1,3-dipolar cycloaddition between the poly(GAP-co-THF) and DNPP at [azide]/[alkyne]/ [CuSO45H2O]/[Na ascrobate]=1/1/0.1/0.5. The triazole with high heat of formation and triazole based salts are promising as energetic materials. The structure and the composition of synthesized copolymers have been characterized by 1H-NMR and GPC. |
