Correlation functions of hard-sphere chain mixtures: integral equation theory and simulation results

Calculations are presented for average segment-segment intermolecular correlation functions of binary hard-sphere chain systems, using the Percus-Yevick integral equation theory. This work is an extension of the particle-particle framework developed previously by pure systems. Analytical expression for the contact values of the correlation functions are a function of chain length, segment diameter and chain density. Monte Carlo simulation data for the correlation functions are obtained and compared with predictions from theory.
