Methodology:
A method based on the principle of material balance for all gas introduced into the cell was employed [1,2].
Sample Information:
- Matheson Gas precision mixture $\pu{50 \pm 0.5\%}$ each $\ce{CO2}/\ce{CH4}$.
Composition verified by GC against a certified Matheson gas reference. - Commercial Kapton H: $d = \pu{1.430 g mL-1}$, $M_{\rm{w}} = \pu{39200}$.
PMDA-ODA: $d = \pu{1.402 g mL-1}$, $M_{\rm{w}} = \pu{36900}$; structure confirmed by IR.
Measurement Errors:
Ambient temperature: No information given.
