Concentrated solutions of polystyrene in dioctylphthalate have been ex
amined as a function of temperature over the concentration range 0.2 t
o 0.9 g/ml. The static screening length and the hydrodynamic screening
length evaluated from the cooperative-diffusion coefficient are compa
red with the predictions of current models.
