Abstract

The osmotic second virial coefficient, B 2 , of off-lattice athermal polymers is calculated using a Monte Carlo procedure. Chain lengths, n, ranging from 3 to 128 are studied. It is found that B 2 /n 2 ∼ n -0.25±0.02 for n→∞ consistent with scaling theories but different from earlier Monte Carlo intimates. The predictions of B 2 from various analytical equations of state for hard chains are tested against the simulation results and found to be quite poor. The generalized Flory dimer equation is modified by forcing it to reproduce the Monte Carlo values for the second virial coefficient; this significantly improves the compressibility factor predictions of the theory at low densities
