Abstract
The UNIFAC and regular solution theory were used to predict solute partition coefficients between polyolefines and ethanol. Both methods were qualitatively correct but not always quantitative for partition coefficients ranging from 0.001 to 10. The regular solution theory was better overall for polar solutes and UNIFAC was better for n-alkanes. Neither method fully accounts for the effects of stearic hindrances and multiple functional groups.
