Abstract
The equilibrium statistical mechanics of a dense fluid composed of flexible polymers is studied with a novel cluster expansion in which the bonding constraints are treated as perturbations. The cluster expansion is shown to be in the same spirit as the widely used Flory–Huggins approximation for the thermodynamics of polymeric fluids. The appropriate continuum analog of the Flory–Huggins approximation is defined in terms of the properties of the zeroth order reference monomeric fluid. A systematic method is provided for computing corrections to this mean field approximation as arising from correlations between the polymer bonds. The results strongly parallel those of our cluster expansion for lattice model polymers. The leading approximation for hard sphere monomers illustrates several facets of the general theory.
