在溶解度参数理论中,聚合物-溶剂的相互作用参数X_1计算式为: X_1=V_1/RT(δ_1-δ_2)~2+β (1)式中V_1为溶剂的摩尔体积,δ_1和δ_2分别为溶剂和聚合物的溶解度参数。经验常数β是作为对Flory组合熵的改进而计入X_1中的。
In the solubility parameter theory, the calculation formula of the polymer-solvent interaction parameter X_1 is: X_1 = V_1 / RT (δ_1-δ_2) ~ 2 + β (1) where V_1 is the molar volume of the solvent, δ_1 and δ_2 are Solvent and polymer solubility parameters. The empirical constant β is included in X_1 as an improvement on Flory’s portfolio entropy.
