ABSTRACT

The pyrolysis kinetics and mechanisms of polymeric organic binder/fuels are largely unknown at the conditions of combustion. New insights into this complex subject are coming to light by the use of T-jump/FTIR spectroscopy. An overview of findings for polymethylmethacrylate, cellulose acetate butyrate, polyethyleneglycol, and hydroxyl-terminated polybutadiene is presented. The main advances are: (1) Rash pyrolysis work has been achieved for the first time in which kinetics and reaction details for the formation of individual products are determined; (2) A switch in the controlling mechanism is observed from bulk-phase decomposition reaction control to desorption control at about 500°C; and (3) Kinetic models are given which contain the desorption-decomposition processes and apply to non-energetic polymers.
