Polymer solvent interaction parameters at infinite dilution (χ1), exchange energy parameter $(\bar{X}_{12})$ , exchange enthalpy (X12), and entropy parameters (Q12), of the PPCS/DGMBE pair were found at studied temperature range according to equation-of-state theory. In the blob theory, dependence of [η] on temperature can be scaled by a master curve in a plot of αη3|τ|M1/2 versus |τ|M1/2 as the polymer coil contracts below the Θ-point, however, it can be scaled by a master curve in a plot of αη−5|τ|M1/2 versus |τ|M1/2 as the polymer coil expands above the Θ-point in an endothermic solubility behavior. Since the studied PPCS/DGMBE system represents exothermic solubility behavior, the master curves of the system were plotted in αη3|τ|M1/2 versus |τ|M1/2 as the polymer coil contracts above the Θ-point and in αη−5|τ|M1/2 versus |τ|M1/2 as the polymer coil expands below the Θ-point. The universal plots of αη(N/N c )1/6 versus N/N c and αη(N/N c )−1/10 versus N/N c were plotted above and below Θ-point, respectively. Springer-Verlag, 2006 Keywords.
