The correlation length (ξ) in benzene solutions of polystrene having two peaks type molecular weight distribution was measured by light scattering. The concentration dependence of ξ is obtained from dilute to semidilute regime. It was shown by theoretical considerations that this dependence could be described by ξ, the second virial coeffisient of osmotic pressure, and the weight fraction of the components. The universal curve for the ξ～C relation was obtained, and this curve was identical to that of the monodisperse systems. A simple relation between the cross-over concentration of the polydisperese system and that of the components was proposed.
