Method/Apparatus/Procedure:

Solubility in the limit of infinite dilution (p → 0) was determined by means of inverse gas chromatography. PS was coated on Fluoropak-80 support. Polymer content was in the range 4.8 % to 13.1 % in the columns having the length 24-71 m. The correction for pressure drop in a column was introduced.

Source and Purity of Materials:

(1) Molecular mass, Mn, of PS = 110 000 - 115 000.

Estimated Errors

Temperature: 1 K.
Solubility: 10%.
