Abstract : This report covers the investigation of the decomposition reactions of epoxy-cured polybutadiene-acrylic acid copolymer (PBAA). Relevant research performed by previous workers and current theories concerning the mechanisms of polymer decomposition in inert and chemically reactive gases are discussed. Results are presented of the pyrolysis experiments carried out in this investigation, utilizing thin-film samples of both the simple polymer and the polymer mixed with burning rate catalysts, ammonium perchlorate and glass beads, and obtained under various conditions of temperature, gaseous environment and pressure. The data obtained is analyzed and conclusions are drawn pertaining to the events occurring at the heated surface of the thin-film polymer or propellant-like material. (Author)
