An analytical solution of the polymer Percus-Yevick approximation for a multicomponent mixture of associating hard spheres, forming star polymer molecules upon association, is derived. Simplified version of the solution, which combines the polymer Percus-Yevick approximation with the so-called ideal chain approximation is used to describe the equilibrium properties of the two-component associating mixture of hard spheres and linear chain molecules. The structure properties of the model are studied at all degrees of association, including the limit of complete association in which the system is represented by the fluid of multiarm polymer star molecules.
