摘要：

Dilute-solution hydrodynamic properties of polystyrene in n-butyl chloride were studied by photon correlation spectroscopy and intrinsic viscosity [eta] measurements. n-Butyl chloride is found to be of moderate solvating power for polystyrene. Chain dimensions estimated from [eta] values via the Burchard-Stockmayer-Fixman approach are in accord with values reported previously in other chloroalkanes but are considerably smaller than values found in cyclohexane. The role of specific solvent effects on unperturbed chain dimensions is discussed.
