SYNTHESIS OF A DIAZIDO TERMINATED ENERGETIC PLASTICIZER

摘要

Glycidyl azide polymer is a hydroxy-terminatedaliphatic polyether containing alkyl azide groups. Such apolymer could be used as a plasticizer in composite explosives,gun and rocket propellants. However, the hydroxyl groups ofthe polymer react with the isocyanate of the curing agent,thereby eliminating any possible plasticizing effect. Thisproblem is overcome by producing a diazido-terminated glycidylazide polymer without terminal hydroxyl groups. This usefulpolymer is produced by reacting polyepichlorohydrin withp-toluenesulfonyl chloride in pyridine, and reacting theresulting tosylated polyepichlorohydrin with sodium azide indimethylformamide.
