In this work, we calculate the direct correlation function and the structure factor of equilibrium polymers in the framework of the PRISM theory. We study especially the effect of the polydispersity and the monomer density on these functions. The intermolecular pair distribution function is compared with simulation results using a recent equilibrium polymer chains model. A scaling analysis is carried out for the direct correlation function.
