Source and Purity of Materials:
- Gas purity: $\ce{CO2}$ 99.99%; $\ce{CH4}$ 99.7%; $\ce{N2}$ 99.999%. PPhPh: synthesized by interfacial polycondensation from phthaloyl chlorides and phenolphthalein. PPhPh-50:50: synthesized by reacting phenolphthalein with a mixture of 50:50 terephthaloyl and isophthaloyl chlorides.
Iso-; $T_{\rm{g}}$ = 522 K, $\rho = \pu{1.304 g mL-1}$
50:50 isomers: $T_{\rm{g}}$ = 522 K, $\rho = \pu{1.298 g mL-1}$
Tere-: $T_{\rm{g}}$ = 572 K, $\rho = \pu{1.297 g mL-1}$.
Estimated Errors:
Ambient temperature: Precision in T: ±0.1 K.
