摘要：

Flory-Huggins parameters have been determined by gas chromatography at 30 °C for ten standard hydrocarbons in ethylene (40%)-propylene (60%) copolymer, s-polyisoprene, and amorphous polypropylene to estimate the polymer solubility parameter (δ2蜴) by the method developed by Dipaola-Baranyi and Guillet. The results are as follows: δ2蜴 = 7.70 ± 0.11 for ethylene-propylene, 7.96 ± 0.10 for cts-polyisoprene, and 7.67 ± 0.16 for polypropylene. The parameters for ethylene-propylene were also estimated by extrapolation from the higher temperature data (63-83 °C) and found to be in good agreement with those estimated directly. © 1979, American Chemical Society.
