The polyamic acid solution was wet cast on a glass substrate heated for one hour at $\pu{353 K}$ under $\ce{Ar}$ to remove the solvent and then imidized by a two-step cure under vacuum (24 hr at $\pu{483 K}$ and four hours at $\pu{553 K}$). $T_{\rm{g}}$ was not reached even though the polymer was heated to $\pu{750 K}$. $\rho = \pu{1.285 g mL-1}$. 124-38-9 1 CO2 InChI=1S/CO2/c2-1-3 CURLTUGMZLYLDI-UHFFFAOYSA-N 44.0095 Carbon dioxide Matheson Gas precision mixture $\pu{50 \pm 0.5\%}$ each $\ce{CO2}/\ce{CH4}$.
