Variables:
Ambient temperature: 298 - 383 K
Prepared by:
Method/Apparatus/Procedure:
Inverse gas chromatography was used for the determination of solubility coefficients. By the measurements correction for the pressure drop in a column was introduced.
Source and Purity of Materials:
- PVTMS was prepared by anionic polymerization (sec.BuLi as a catalyst) and had molecular mass about 500,000 and a density 0.898 g/cc.
