N2 - A general off-lattice microscopic theory of the equilibrium properties of polymer mixtures is developed based on reference interaction site model integral equation methods. A derivation of a random-phase-approximation like scattering function is presented along with a fully microscopic, general formula for the effective X parameter measured in small-angle neutron-scattering experiments. Numerical results for X of an athermal, Gaussian-chain polymer binary blend are presented as a function of concentration, packing fraction, molecular weight, and structural asymmetry.
