中文摘要: |
用基团贡献法通过拆分计算出“N ”的基团贡献数据 F d i 、 F p i 、 E h i 值,并对杂萘联苯聚醚砜及磺化杂萘联苯聚醚砜的三维溶解度参数进行计算,得出了不同磺化度磺化杂萘联苯聚醚砜三维溶解度参数各分量 δ d、 δ p和 δ h的计算公式.结果表明,随着磺化度的提高,磺化杂萘联苯聚醚砜的三维溶解度参数中 δ h分量显著提高, δ p分量略有增加,而 δ d分量变化不明显,磺化聚合物的溶解区域向高 δ h方向移动.计算结果与实验结果吻合较好,对以后实验中溶剂的选择有重要的指导意义. |
英文摘要: |
The group contribution factors F d i , F p i and E h i of “N ” were calculated by group contribution method. The three-dimension solubility parameters of poly (phthalazinone ether sulfone) (PPES) and sulfonated poly (phthalazinone ether sulfone) (SPPES) were calculated, and the mathematic formulations of solubility parameters components δ d, δ p and δ h at different sulfonation degrees were also suggested. The results indicate that as the sulfonation degree increases, the hydro-component ( δ h) of SPPES three-dimension solubility parameters increases obviously, the polar component ( δ p) increases smoothly, and the change of dispersive component ( δ d) can be neglected, the solubility area of SPPES moves toward high hydro-component ( δ h) area. The calculation results are in good accordance with the experimental ones, and these results are important for the solvents selection of SPPES in future experiments. |
