Flash pyrolysis of structurally different hydroxyl-terminated polybutadiene polymers (HTPB) was conducted at 600°C/s to constant temperatures in the 450°–609°C range under 2 and 11 atm of applied pressure. T-Jump/FTIR spectroscopy was used. With chemometric procedures based on the entire mid-IR spectrum, 13 gaseous products representing at least 70% of the polymer were identified and quantified. Contrary to previous indications that butadiene and 4-vinyl-l-cyclohexene dominate, the trans-butadiene oligomers are major products. These oligomers are probably responsible for smoke formation. The product concentrations are sensitive to the temperature below 500°–530°C and 2 atm Ar, but are relatively insensitive to the temperature above 500°–530°C.
