ABSTRACT:
Poly(diethylene glycol-4,7-dinitrazadecane-dioate), P-DEND), is synthesized y the Michael addition of ethylene dinitramine to methyl acrylate to yield the intermediate compound dimethyl-4,7-dinitrazadecane-dioate (DMDND). DMDND is reacted for a period of about 18 hours with diethylene glycol (DEG) at about 85.degree. C. in presence of a p-toluenesulfonic acid catalyst to yield P-DEND. The product (P-DEND) is purified by passing it through a silica gel column using methylene chloride as solvent. The average molecular weight of P-DEND ranges from about 1500-2000. P-DEND is shown to be compatible with stabilized nitroglycerin for use as an energetic polymer binder for high performance propellants.
