Preliminary research of composite rocket propellants with hexogen and titanium oxide powder [PDF]

Scientific Technical Review, 2018
Composite solid propellants based on ammonium perchlorate/hydroxyl-terminated polybutadiene/isophorone dyisocyanate including two levels of hexogen (RDX) are presented in this paper. The mass of RDX increased in relation to oxidant, with constant bimodal

Estudo da decomposição térmica de propelente sólido compósito de baixa emissão de fumaça Study of thermal decomposition of a smokelles propellant

Química Nova, 2008
The thermal decomposition of hydroxyl-terminated polybutadiene (HTPB)/ammonium nitrate (AN) based propellants, so called smokeless formulations, and raw materials were investigated by differential scanning calorimetry (DSC) and thermogravimetry (TG). The

Functionalizations of C─H and C═C Bonds in Polyolefins Catalyzed by Transition‐Metal Complexes

Angewandte Chemie Novit, Volume 1, Issue 2, October 2025.
Post‐polymerization modification of polyolefins is a powerful strategy to create otherwise inaccessible materials; transition‐metal‐catalyzed functionalizations of C─H and C═C bonds enable site‐, chemo‐, and stereoselective installation of groups to impart unique properties.
