In this study, thermophysical properties like Flory-Huggins interaction parameter ( X ), weight fraction infinite dilution activity coefficient (), heat of solution (Hs) and diffusion coefficient (D1) were determined for polyisobutylene (PIB), antishock polystyrene and styrene-butadiene rubber (SBR) with benzene, cyclohexane, n-hexane and n-pentane using gas chromatography (GC). The experiments were performed for antishock polystyrene at 313.3 to 402.3 K, for SBR at 343.3 to 363,2 K and for PIB at two different temperatures 312.1 K and 323.1 K • The chromatographic retention data obtained at these temperatures were used to determine the above mentioned thermophysica1 properties of polymer solvent pairs.
