Self-consistent Ornstein-Zernike approach to polymer fluids. (English) Zbl 1039.76002

Summary: We study Flory-Huggins lattice polymers using a self-consistent Ornstein-Zernike approach. The results are compared with those derived from classical mean-field theory. A simple continuum-space (i.e. off-lattice) extension of the Flory-Huggins model is also proposed and studied.
