导出了平衡时可混溶聚合物共混物的表面组成和表面能较低组分的表面过量（吸附量）的简单解析表达式。在实际情况中，预计总表面过剩量更强烈地取决于两种聚合物链段之间的弗洛里-哈金斯相互作用参数的值，而不是共混物组分之间的表面能差异。
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.
