Polymer combustion is a highly complicated process where
chemical reactions may occur not only in the gas phase,
but also in the condensed phase as well as at the
solid-gas interphase. The complication arises due to
the coupling between the condensed phase and gas phase
phenomena. While some polymers form a char layer during
combustion, others exhibit swelling, bubbling, melting,
sputtering, and multi-stage combustion. The combustion
of polymeric materials is related to many applications
including solid and hybrid rocket propulsion, and of
recent interest, waste incineration.
