Abstract
Thermo-oxidative degradation of hydroxy-terminated polybutadiene (HTPB ) and poly(butadiene-acrylonitrile-acrylic acid) terpolymer (PBAN) bin ders was studied in the presence of varying amounts of ammonium perchl orate (AP). It was found that the effect of AP on the nature and compo sition of the pyrolyzates was similar to the effect of increase in pyr olysis temperature. Activation energy for thermal degradation was foun d to be about 52 kJ/mol for both the polymers. The results are discuss ed in terms of a linear pyrolysis model.
