Abstract

Upper critical solution temperatures (UCSTs) for liquid-liquid demixing in a set of mixtures of linear alkanes (pentane (N1=5) to pentacontane (N1 =50) with an oligostyrene (1241 amu, N2=12) are reported. We find strong correlation between the Hildebrand solubility parameters of the alkanes and the UCST. Correlations are developed which enable predictions concerning the miscibility of mixtures of compounds with longer chains.
