摘要：

Measurements were made of infinite dilution diffusion coefficients of volatile liquids in amorphous polymers at elevated temperatures, using inverse gas chromatography. The liquids used were benzene, toluene, ethylbenzene, and n-decane. The polymers used were polystyrene and poly(vinyl acetate), and temperatures ranged from 30 degree C to 120 degree C above the glass transition temperature of the polymers.
