Recovery of aluminum from composite propellants [PDF]

, 1980
Aluminum was recovered from solid rocket propellant containing a small amount of oxidizer by depolymerizing and dissolving propellant binders (containing functional or hydrolyzable groups in a solution of sodium methoxide) in an alcohol solvent ...

Chemorheological Kinetic Modeling of Uncatalyzed Hydroxyl‐Terminated Polybutadiene and Isophorone Diisocyanate

Macromolecular Materials and Engineering
Catalysts are often employed to enable nonisothermal reaction kinetic studies when tracking cure progression of polyurethane reactions. However, when quickly reacting, catalyzed materials are prepared through mixing followed by the addition of fillers or

Elucidation of the dynamics for hot-spot initiation at nonuniform interfaces of highly shocked materials [PDF]

, 2011
The fundamental processes in shock-induced instabilities of materials remain obscure, particularly for detonation of energetic materials. We simulated these processes at the atomic scale on a realistic model of a polymer-bonded explosive (3,695,375 atoms/

Chitin based polyurethanes using hydroxyl terminated polybutadiene, part III: Surface characteristics [PDF]

International Journal of Biological Macromolecules, 2013
Hydroxy terminated polybutadiene (HTPB)-chitin based polyurethanes (PUs) with controlled hydrophobicity were synthesized using HTPB and toluene diisocyanate (TDI). The prepolymer was extended with different mass ratios of chitin and 1,4-butane diol (BDO). The effect of chitin contents in chain extender (CE) proportions on surface properties was studied

Synthesis and Characterization of Methacrylamide‐Based Block Random Copolymers via Amine Functionalization of Polystyrene‐Block‐Poly(Pentafluorophenyl Methacrylate) Toward Enhanced Amenability to Manufacturing Criteria in Nanolithography

Macromolecular Chemistry and Physics, Volume 226, Issue 23, December 5, 2025.
Polystyrene‐block‐poly(pentafluorophenyl methacrylate) (PS‐b‐PPFMA) is functionalized with primary amines to develop A‐block‐(B‐random‐C) block copolymers (BCPs). These BCPs exhibit high thermal stability and circumvent sources of undesired side reactions upon heating on account of its methacrylamide functionality.

Coating of High Melting Explosive Particles by Nitrotriazolone to Formulate Composite Nanoparticles by Spray Flash Evaporation

Propellants, Explosives, Pyrotechnics, Volume 50, Issue 11-12, Page 32-39, December 2025.
ABSTRACT The balance between performance and safety of high explosives is at the heart of the current studies, and new ways of combining safety and performance have hence been elaborated. This study focuses on a mixture of 3‐nitro‐1,2,4‐triazol‐5‐one (NTO) and octogen (high melting explosive [HMX]).
