The effect of the atmosphere on the thermal degradation
and gasification of bulk polymeric materials is not
fully understood with respect to ignition and flame
spread. It is of interest to know whether molecular
oxygen influences these aspects of polymer flammability
through direct attack on the condensed phase. To
investigate, at the molecular level, the effect of the
concentration of atmospheric oxygen on the decomposition
of bulk PMMA at different incident heat flux levels
simulating radiative heating on the surface by fires.
