    Estimation of Hansen Parameters of PES , PSF and Their Sulfonated Products with Various Degrees of Sulfonation by Group Contribution Method

      摘要
    • 摘要: 采用基团贡献法对聚醚砜、聚聚砜及其不同磺化度磺化产物的溶度参数分量δd、δp和δh进行了估算，提出了计算其任意磺化度产物的溶度参数的通式，同时补充了砜基和1，2，4－三取代苯基的基团贡献值Fdi,Fpi和Ehi并提出了计算聚合物溶度参数极性分量（δp)的数学模型，估算得到的结果与文献中的实验结果相吻合。

       

      Abstract: The solubility parameters (Hansen parameters ) of polyethersulfone(PES), polysulfone(PSF) and their sulfonated products at various degree of sulfonation(D.S.) are estimated by using group contribution method. The group contribution components of -SO 2- a
