采用浊度滴定法测定和基团贡献法估算了酚酞基聚醚砜的溶解度参数。基团贡献法估算与浊度滴定法测定的结果相吻合。测得酚酞基聚醚砜的溶解度参数为20.76J1/2mL-1/2,这对研究其溶液性质和应用有重要的意义。
The solubility parameters of phenolphthalein polyethersulfone were estimated by turbidimetric titration and group contribution method. The group contribution method is consistent with the turbidity titration method. The measured solubility parameter of phenolphthalein polyethersulfone is 20.76J1 / 2mL-1/2, which is of great significance for studying the solution properties and application.
