Abstract

Thermo‐oxidative degradation of hydroxy‐terminated polybutadiene (HTPB) and poly(butadiene‐acrylonitrile‐acrylic acid) terpolymer (PBAN) binders was studied in the presence of varying amounts of ammonium perchlorate (AP). It was found that the effect of AP on the nature and composition of the pyrolyzates was similar to the effect of increase in pyrolysis temperature. Activation energy for thermal degradation was found to be about 52 kJ/mol for both the polymers. The results are discussed in terms of a linear pyrolysis model.
