摘要：

The vapor-liquid equilibria of HCFC 142b, HFC 134a, HFC 125 and isopropanol in polystyrene were determined in a closed high pressure vessel at temperatures up to 220 degrees C. Complete solubility maps are presented for each blowing agent, including conditions for phase separation in the polystyrene phase. In order of decreasing solubility, the blowing agents rank isopropanol > HCFC 142b > HFC 134a > HFC 125. In the cases of isopropanol and HFC 134a, some solubility results obtained by the vapor pressure method and those using a high-pressure electrobalance are compared.
