Application of the Ornstein-Zernike Formalism to Polymer and Copolymer Blends

摘要

The Ornstein Zernike formalism is shown to be applicable to polymer and copolymer blends. Direct correlation functions are obtained from the solution problem by using a simple procedure which was suggested before (M. Benmouna, H. Benoit and W. Wu, to be published in Macromolecules). This procedure consists essentially of replacing the volume fraction of solvent by the quantity phi/sub c/N/sub c/P/sub c/(q) where phi/sub c/, N/sub c/ and P/sub c/(q) are the volume fraction, the degree of polymerization and the form factor as a function of momentum transfer q, respectively.
