With the increasing concentration of SAN , the melting points of a semicrystalline polymer PCL depress in the PCL / SAN blends . By means of Flory-Huggins equation , the interaction parameter ( x23 ) between these two macromolecules has been evaluated from the melting point depression .
而且随着含量的增加，半结晶高聚物的熔点下降，利用Flory-Huggins方程计算出共混体系的相互作用参数x（23）计算结果表明该体系是热力学相容的。
