Abstract Bonding between ammonium perchlorate (AP) and hydroxy‐terminated polybutadiene (HTPB), constituting a nonreinforcing filler system, has been studied in the presence of a unique bonding agent (BA)–a switter ion molecule, 2,4‐dinitrophenylhydrazone derivative of 1,1′‐bisacetylferrocene (DNPHD AF). Extensive conjugation and a permanent ionic character makes the DNPHD AF to bond strongly with the ionic oxidizer AP. Through its terminal OH group, HTPH bonds with the NO 2 groups of DNPHD AF. Bonding sites in the molecules have been located from IR studies and from the first‐order rate constant measurements of the bonding of DNPHD AF and other model BAs with HTPB and AP. The bonding ability of DNPHD AF is further evidenced from SEM micrographs.
