Method/Apparatus/Procedure:
The solubility was measured by means of an apparatus of hydrostatic weighing the principle of which had been described in Ref. (1).
Source and Purity of Materials:
PMP of the grade DX-810 had a density of 0.82-0.83 g/cc and crystallinity 90 %. All the gases were "chemically pure" according to the Soviet Standard.
Estimated Errors:
Solubility: 1.5%
