The correlation function presented by Debye et al. for characterizing the random two-phase structure in solids is further extended by considering an effect of partial ordering to describe the statistical features in phase separation structures of polymer blends. The new correlation function is in the form γ(r) = exp( - r/a0)cos(q0r) with two parameters. The scattering intensity distribution calculated from this function can predict a maximum whose sharpness and position are characterized by a 0 and q0. Good agreement was achieved between the calculated intensity and measured small-angle light scattering curve from phase-separated poly(methyl methacrylate)/poly(vinyl acetate) blends.
