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 ...

Rheological Characterization of Low and High‐Solids‐Loaded Suspensions Using Capillary Rheometry
Propellants, Explosives, Pyrotechnics, Volume 51, Issue 1, Page 144-156, January 2026.ABSTRACT Controlled extrusion of viscous liquids with suspended solids depends critically on rheology. The rheology of a binder (9:1 mass ratio of cellulose acetate butyrate (CAB) to triacetin with a 55 wt.% diethyl ketone balance) loaded with dilute (0–15 wt.%) and concentrated (≥50 wt.%) granulated sugar loadings from three particle size ...

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

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.

Trifluoromethylation of carbonyl groups in aromatic poly(ether ketone)s: formation of strongly polar yet surface-hydrophobic poly(arylenenecarbinol)s [PDF]
, 2018 Fluoride-catalyzed reactions of trimethyl(trifluoromethyl)silane with a range of aromatic poly(ether ketone)s, both amorphous and semi-crystalline, proceed quantitatively in THF to yield soluble, amorphous polymers in which the carbon-silicon bond of ...
