The effect of sample thickness on its limiting oxygen concentration (LOC) was investigated for poly-methyl methacrylate and poly-carbonate with different thickness. For both materials, the LOC was different according to the thickness in microgravity regime although the sample was thin enough to be regarded as thermally-thin. This result implied that there was some heat conduction into the sample although the sample was thin. On the other hand, the LOC of PMMA was almost the same in kinetic regime for each thickness whereas the LOC of PC was different in kinetic regime; the thicker the sample was, the larger the LOC was. It was thought that the difference was resulted from the difference of their pyrolysis temperature.
