Simple, analytical expressions are derived for the surface composition and surface excess (adsorbed amount) of the lower surface energy component of a miscible polymer blend at equilibrium. In practical cases, the total surface excess is predicted to depend more strongly on the value of the Flory-Huggins interaction parameter between the segments of the two polymers than on the difference in surface energies between the components of the blend.
