Polarized light scattering in bulk polymers is positively correlated with the intensity of dielectric fluctuation and the size of the heterogeneous structure, which is expressed by a correlation length. In this study, the influence of dielectric fluctuation was independently investigated for the first time on the basis of the difference in the light-scattering properties between two random copolymers - methyl methacrylate (MMA)/pentafluorophenyl methacrylate (PFPMA) and MMA/phenyl methacrylate (PMA). These copolymers have similar correlation lengths but show different intensities of dielectric fluctuation. When the difference of the mean-square average of the fluctuations of all dielectric constants between the copolymers was 105 × 10-10, the difference in isotropic light-scattering loss was 425 dB/km at 633 nm.
