Polymer-Solvent Interaction from Gas-Liquid Chromatography. Initial Experiments with Open Tubular Columns

摘要

Open tubular columns coated with polymer above its glass transition temperature have been used for measuring polymer-solvent interactions with gas-liquid chromatography. Consideration is given to the effect of polymer-film thickness on polymer-solvent interaction. Experimental retention volumes are reported for a number of solvents with poly (isobutylene) at 75#xB0;C and with poly(dimethylsiloxane) at 70#xB0;C and compared with those obtained using packed columns.
