Claims
- 1. A method of preparing a cast homogeneous, insensitive energetic composition comprising the steps of:
- melting a thermoplastic elastomer at a temperature from about 100.degree. C. to about 150.degree. C.;
- dissolving a plasticizer in the molten thermoplastic elastomer to form plasticized thermoplastic elastomer, said plasticized thermoplastic elastomer being capable of dissolving a nitroaliphatic oxidizer;
- adding nitroaliphatic oxidizer to the molten plasticized thermoplastic elastomer and dissolving the oxidizer therein to form a castable composition;
- casting the composition to form a shaped article; and cooling under conditions effective to provide an energetic composition having only a small amount or no crystallites of said nitroaliphatic oxidizer.
- 2. A method according to claim 1 in which the nitroaliphatic oxidizer is added to the molten elastomer in increments.
- 3. A method according to claim 2 further including the step of cooling the plasticized elastomer to temperature below 120.degree. C. before adding the oxidizer.
