Zusammenfassung: | Experimental data for the phase behavior of poly(ε-caprolactone) (PCL) in mixtures of carbon dioxide with dichloromethane or chloroform over a range of external conditions are presented. Cloud point pressures were measured using a variable-volume view cell as functions of temperature, carbon dioxide-to-organic solvent ratio, and concentration of PCL. A high-molecular weight (M w = 124 200) PCL was used in all studies and at mass fractions of 0.01, 0.02, and 0.03. For the adequate control of the carbon dioxide-to-organic solvent ratio, a new experimental procedure was employed that allows for a good control of the composition. |
