摘要
采用基团贡献法对聚醚砜、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。
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- and [JJ1,Z;3,YS;4,Y] are complemented,and the mathematical model in calculating the polar component of Hansen parameters of polymers is put forward. The estimated results are in accordance with the experiments in other essays.
