Abstract

Intrinsic viscosities, [eta], of poly(p-chlorostyrene) (PPCS) in diethylene glycol monobutyl ether (DGMBE) which exhibits an exothermic solubility behavior with the polymer were measured using an Ubbelohde type capillary viscometer between 25 and 85 degrees C. Polymer solvent interaction parameters at infinite dilution (chi(1)), exchange energy parameter ((X) over bar (12)), exchange enthalpy (X-12), and entropy parameters (Q(12)), of the PPCS/DGMBE pair were found at studied temperature range according to equation-of-state theory.
