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