STABILIZED NITROCELLULOSE-BASED PROPELLANT COMPOSITION

摘要

The present invention concerns a nitrocellulose-based propellant composition comprising:;(a) a nitrate ester based propellant consisting of nitrocellulose alone (single base) or in combination at least with a blasting oil (double or higher base); and;(b) a stabilizer consisting of a general formula (I):;;Wherein the stabilizer combines efficient, long term stability of the nitrocellulose-based propellants composition without formation of any detectable amounts of carcinogenic or mutagenic by-products, such as -NNO groups.
