Abstract

The multi-density Ornstein-Zernike (MOZ) integral equation theory was used to model a homonuclear sticky hard sphere (SHS) chain fluid in the context of the polymer Percus-Yevick (PPY) and ideal chain approximations. It was found that for a nonathermal system, the difference of structural properties between a monodisperse and a polydisperse system is not of significance only at intermediate and high densities. The Helmholtz energy, pressure, and phase coexistence of the monodisperse SHS chains were computed via the energy route.
