  • Process for obtaining a hydroxy-ended glycidil azine polymer
    Patent number: 5319037
    Abstract: A process for obtaining a hydroxy-ended glycidyl azide polymer (GAP). The process consists in reacting polyepichlorohydrin (PECH) with a metallic azide in the presence of an organic solvent having a parameter of solubility comprised between 21 and 23.5 (MPa).sup.1/2 such as DMA or NMP. The use of any of the solvents mentioned sharply reduces the reaction time needed for substituting azide groups for the chlorine present in the PECH. Said reaction times can be less than 4 hours when NMP is used or less than 6 hours when DMA is used. The GAP thus obtained having a functionality equal to or above 2 can be used as energetic bonding agent in the formulation of solid propellants for rockets.
