Using the Svetlov theory, it is shown that the ratio of intrinsic flow birefringence to intrinsic viscosity is independent of the magnitude of the hydrodynamic interaction, in the case where the latter is consistently pre-averaged. The intrinsic birefringence has been calculated on Tagami's model for stiff chains, and the results are compared with earlier theories.
