53807774, Jan 10, 1995

Filed:

Mar 28, 1994

Appl. No.:

8/224098

Inventors:

Rodney Willer - Newark DE
Alfred G. Stern - Elkton MD
Robert S. Day - Newark DE

Assignee:

Thiokol Corporation - Ogden UT

International Classification:

C07C20304
C08G 5914
C08K 532
C08L 7102

US Classification:

524186

Abstract:

This invention is first, a difunctional poly(glycidyl nitrate) oligomer (PGN oligomer), second, nitrated PGN oligomer and third, the use of the nitrated PGN oligomer as a plasticizer, particularly as a plasticizer for binders used in and/or as energetic formulations. Examples of energetic formulations are propellants, pyrotechnics and explosives and other such compositions. More particularly, this invention is a difunctional poly(glycidyl nitrate) oligomer of the formula ##STR1## where n is 0 to 3, having a M. sub. n of from about 304 to about 994. Another embodiment is the nitrated difunctional poly(glycidyl nitrate) oligomer of the formula ##STR2## where n is 0 to 3, having a M. sub. n of from about 394 to about 1084. This invention also comprises a plasticizer for binder compounds, namely, the nitrated PGN oligomer above; preferably the plasticizer above is used wherein the binder compound is used in energetic formulations; and preferably the binder compound is an energetic compound; more preferably the energetic formulation is selected from the group consisting of propellants, pyrotechnics and explosives.

International Classification:

C07D27108
C06R 2534

US Classification:

149 92

Abstract:

The energetic salts of 3-nitramino-4-nitrofurazan have a desirable combination of desirable properties such as sufficiently high densities, and low or no hydrogen content. The salts are useful as ingredients in various propellant, explosive, gassifier, and pyrotechnic compositions. 3-Nitramino-4-nitrofurazan is itself a useful energetic compound and is also useful in the synthesis of still further energetic compounds.

Assignee:

Thiokol Corporation - Ogden UT

International Classification:

C06B 4510

US Classification:

149 199

Abstract:

Improved thermoplastic elastomer compositions having improved processing and mechanical characteristics without requiring addition of excessive quantities of plasticizer comprise at least one thermoplastic elastomer loaded with a crystalline modifier having a relatively low melting point. The modifier can be liquid at the processing temperature, resulting in increased ease in handling of the product. An exemplary crystallizable modifier is an alkylated pentacycloundecane dimer.

US Classification:

528408

Abstract:

Isotactic poly(glycidyl nitrate) useful in solid propellants is produced by polymerizing chiral (R) glycidyl nitrate or its enantiomer, (S) glycidyl nitrate. Chiral (R) glycidyl nitrate or its enantiomer is prepared by sequential treatment of chiral (S) glycidyl tosylate or its enantiomer with nitric acid and sodium hydroxide. Chiral (S) glycidyl tosylate or its enantiomer, (R) glycidyl tosylate, can be produced by Sharpless epoxidation of allyl alcohol or by direct tosylation of commercially available chiral glycidol. Likewise, chiral (R) glycidyl nitrate or its enantiomer, (S) glycidyl nitrate, can be prepared direcly via nitration of (S) or (R) glycidol, respectively.
