Abstract
The modified square well potential is combined with perturbed-hard-trimer-chain (PHTC) EOS to predict the solubility parameters of
several fluids including alkanes, refrigerants and molten polymers. The performance of the proposed model has been evaluated by
predicting the solubility parameters of 12 hydrocarbons, 3 refrigerants and 12 polymers. Out of 263 data points for hydrocarbons and
refrigerants, the average absolute deviations percent (AAD%) of the predicted densities and solubility parameter from the experimental
ones were found to be 1.74% and 1.09%, respectively. Additionally, out of 1993 data points of 12 polymers, the AADs% of the predicted
densities were found to be 0.43% and out of 60 data points examined, the AAD% of the predicted solubility parameters from the
experimental ones were found to be 0.56%, respectively.
