Methodology:
A McBain balance with a quartz spring was used in sorption measurement.
Sample Information:
- PVTMS synthesized in the presence of $\ce{BuLi}$ had $M_{\rm{w}}$ = 608 000 and $M_{\rm{n}}$ = 416 000. All the gases were chromatographically pure.
Measurement Errors:
Mass concentration (m/v) (1): 10%.
System Components:
- Xenon, $\ce{ Xe }$; [7440-63-3] NIST WebBook
- Ethyne, $\ce{ C2H2 }$; [74-86-2] NIST WebBook
- Ethene, $\ce{ C2H4 }$; [74-85-1] NIST WebBook
