Azide and Alkyne Terminated Polybutadiene Binders: Synthesis, Cross-linking, and Propellant Studies

, 2014
In composite solid propellants, the fuel and oxidizer are held together by a polymer binder. Among the different types of polymeric binders used in solid propellants, hydroxyl terminated polybutadiene (HTPB) is considered as the most versatile.

A Review on Vehicle Tire Elastomers and Tire Wear Particles: Composition, Degradation Mechanisms, Analytical Methods, and Predictive Multiscale Computational Modeling

Advances in Polymer Technology, Volume 2026, Issue 1, 2026.
The study of the properties, chemical composition, and degradation patterns of rubber materials used in vehicle tires remains a complex and interdisciplinary task. Rubber for tires—more precisely, complex mixtures of elastomers containing fillers, plasticizers, binders, and other additives—is a condensed chemically active material, the composition and ...

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]).

Enhancing energetic features of HTPB binder through nitro-functionalization and nitrocellulose doping

FirePhysChem
This study presents a double modification strategy to enhance hydroxyl‑terminated polybutadiene (HTPB) properties as an energetic binder. HTPB was chemically nitrated to obtain nitro-HTPB (NHTPB), then blended with nitrocellulose (NC) at different ratios
