Ionizing Radiation Sensitivity of Hydroxyl Terminated Polybutadiene Solid Propellant

, 2019
The effects of ionizing radiation on hydroxyl-terminated polybutadiene (HTPB) solid propellant are investigated to assess its sensitivity to electron radiation. Investigation into the radiation sensitivity of HTPB propellant is needed to assess potential

Synthesis of propellant grade HHTPB by hydrogenation of HTPB using Pd-activated charcoal as catalyst

FirePhysChem
To derive more performance from the conventional composite propellant based on hydroxyl-terminated polybutadiene (HTPB) and ammonium perchlorate (AP), it is envisaged to hydrogenate HTPB, which increases the H/C (hydrogen to carbon ratio) of the base ...

Glycidyl Azide-Butadiene Block Copolymers: Synthesis from the Homopolymers and a Chain Extender

, 2017
Glycidyl azide polymer (GAP) is an energetic alternative to hydroxyl-terminated polybutadiene (HTPB), but has poorer mechanical properties. Since HTPB-GAP mechanical blends are markedly biphasic, the use of block copolymers may be the solution to join ...
