Integral equation theory of polymer blends

Conference ·
OSTI ID:5682676

An off-lattice microscopic statistical mechanical theory of the equilibrium properties of polymer mixtures is developed based on modern integral equation methods. A rigorous derivation of the RPA scattering function is presented along with a fully microscopic, exact formula for the effective chi-parameter measured in SANS experiments. Numerical results for a hard core Gaussian polymer binary blend are presented. Chi is found to be a sensitive function of concentration, packing fraction, molecular weight, and structural asymmetry.
