Abstract
Liquid-liquid demixing in propionitrile-polystyrene solutions has been observed (-2 < P/MPa < 4) using a Berthelot tube technique. The exper imental isopleths join smoothly to ones gathered at positive pressure by another technique. The equation of state used to describe the trans itions thus appears to be valid across the entire liquid range. (C) 19 94 John Wiley & Sons, Inc.
