Method/Apparatus/Procedure:
The conventional McBain sorption spring balance was used.
Source and Purity of Materials:
- All the gases had a purity $\pu{\gt 99.9\%}$.
- The co-polymer was prepared via oxidative co-polycondensation of two monomers. The purity of product $\pu{99.9\%}$, it had $d = \pu{1.10 g mL-1}$ and $T_{\rm{g}} = \pu{754 K}$.
Estimated Errors:
Ambient temperature: ±0.1 K
